This book consists of a series of lectures introducing what the author believes to be the theoretical minimum for the understanding of nuclear spin dynamics, the branch of physics underpinning magnetic resonance techniques such as NMR and MRI. Spin dynamics ultimately concern the study of the state and time evolution of systems made by a large collection of particles possessing spin, one of the most subtle and indeed fascinating concepts in relativistic quantum mechanics and whose understanding requires a mix of quantum mechanics, Hamiltonian dynamics and advanced mathematics. Written in the concise and direct style appropriate for university lectures, this book is addressed to both undergraduate and postgraduate students who are approaching magnetic resonance studies and want to reach the theoretical minimum required to understand the wider topic and its main applications. The book is suitable for researchers who work in the field of magnetic resonance and want to know more about its theoretical fundamentals. Finally, built as a complete set of 12 lectures and 4 workshops, the book can act as a solid reference to lecturers of magnetic resonance university modules. Trained in a world-leading research laboratory internationally recognised for its contributions to the NMR field, the author has a track record in theoretical and methodological developments of nuclear spin dynamics. In this book, he tries to merge his passion for the understanding of physics through its mathematical rendering with his personal quest for the elegance of a clean, clear and satisfactory explanation.

NMR DATA PROCESSING

Jeffrey C. Hoch and Alan S. Stern

Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful nondestructive technique for exploring the structure of matter. In recent years, NMR instrumentation has become increasingly sophisticated, and the software used to acquire and process NMR data continues to expand in scope and complexity. This software has always been difficult to understand, and, until now, it seemed likely to remain that way.

NMR Data Processing examines and explains the techniques used to process, present, and analyze NMR data. It provides a complete account of the fundamentals of spectrum analysis and establishes a framework for applying those fundamentals to real NMR data. It also details, in clear and concise language, the basic principles underlying the complex software needed to analyze the data.

Two chapters are devoted to the fundamentals and applications of discrete Fourier transform (DFT) in NMR, which was crucial to the development of modern NMR spectroscopy. A large part of the book focuses on increasingly important non-DFT methods, which obtain higher sensitivity and resolution. Other topics covered include:

• Data formats
• Processing for multidimensional experiments
• Parametric modeling of NMR signals
• Standard techniques—apodization, zero-filling, the Hilbert transform
• Artifacts—aliasing, leakage, solvent signals
• Advanced processing techniques—LP, MaxEnt, Bayesian analysis

Jeffrey C. Hoch and Alan S. Stern conclude their in-depth look at this rapidly growing field by exploring methods for analyzing processed data, including visualization, quantification, and error analysis. Readers are provided with a solid foundation for developing new methods of their own.

NMR Data Processing is an important tool for students learning basic principles for the first time, technicians troubleshooting data processing problems, and professional researchers developing new techniques. It will help all NMR users acquire a true grasp of the methods behind the process, avoid the pitfalls of misapplication and misinterpretation, and exploit the full power of NMR software.

The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. Over recent years, a number of powerful two-dimensional NMR techniques (e.g. HSQC, HMBC, TOCSY, COSY and NOESY) have been developed and these have vastly expanded the amount of structural information that can be obtained by NMR spectroscopy. Improvements in NMR instrumentation now mean that 2D NMR spectra are routinely (and sometimes automatically) acquired during the identification and characterisation of organic compounds. Organic Structures from 2D NMR Spectra is a carefully chosen set of more than 60 structural problems employing 2D-NMR spectroscopy. The problems are graded to develop and consolidate a student s understanding of 2D NMR spectroscopy. There are many easy problems at the beginning of the collection, to build confidence and demonstrate the basic principles from which structural information can be extracted using 2D NMR. The accompanying text is very descriptive and focussed on explaining the underlying theory at the most appropriate level to sufficiently tackle the problems. Organic Structures from 2D NMR Spectra * Is a graded series of about 60 problems in 2D NMR spectroscopy that assumes a basic knowledge of organic chemistry and a basic knowledge of one-dimensional NMR spectroscopy * Incorporates the basic theory behind 2D NMR and those common 2D NMR experiments that have proved most useful in solving structural problems in organic chemistry * Focuses on the most common 2D NMR techniques including COSY, NOESY, HMBC, TOCSY, CH-Correlation and multiplicity-edited C-H Correlation. * Incorporates several examples containing the heteronuclei 31P, 15N and 19F Organic Structures from 2D NMR Spectra is a logical follow-on from the highly successful Organic Structures from Spectra which is now in its fifth edition. The book will be invaluable for students of Chemistry, Pharmacy, Biochemistry and those taking courses in Organic Chemistry.

Dynamic Spin Chemistry Edited by Saburo Nagakura, Hisaharu Hayashi and Tohru Azumi Because of increasing concerns over the effects of electromagnetic radiation on the human body, it has become essential to understand how chemical and biological reactions are affected by magnetic fields. Dynamic Spin Chemistry focuses on theoretical and experimental research showing the great influence on the dynamic behavior of molecules due to external magnetic fields, such as magnetic quenching of gaseous fluorescence, effects on chemical reaction rates and chemically induced dynamic nuclear and electron polarization. This book discusses both the theoretical and experimental foundations of dynamic spin chemistry, as well as its future trends. After the introductory chapter, the next three chapters discuss magnetic field effects and magnetic isotope effects on chemical reactions in solution and on the dynamic behavior of excited molecules in the gas phase. Subsequent chapters deal with the effects on chemical equilibria under large fields; spin spectroscopy; chemically induced dynamic electron polarization (CIDEP) studies and reaction yield-detected ESR. This book will be of interest to researchers and graduate students in pure and applied chemistry, physics or biology having an interest in photochemistry, photophysics or photobiology.

This book offers detailed insights into spin transfer torque (STT) based devices, circuits and memories. Starting with the basic concepts and device physics, it then addresses advanced STT applications and discusses the outlook for this cutting-edge technology. It also describes the architectures, performance parameters, fabrication, and the prospects of STT based devices. Further, moving from the device to the system perspective it presents a non-volatile computing architecture composed of STT based magneto-resistive and all-spin logic devices and demonstrates that efficient STT based magneto-resistive and all-spin logic devices can turn the dream of instant on/off non-volatile computing into reality.

Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful analytical techniques available in modern science, and is widely used by chemists, biochemists, physicists and physicians. Nuclear Magnetic Resonance: Concepts and Methods examines the physical and mathematical features of liquid state NMR spectroscopy which underpin the numerous important applications of the technique, before exploring these applications in depth. Detailed examples and figures presented throughout the text enable the student to understand conceptually challenging ideas. Advanced mathematical and quantum mechanical developments are presented in such a way that they can be skipped on a first reading, enabling the reader to concentrate on the key concepts underlying such important topics as Fourier Transform NMR spectroscopy, product-operator formalism, signal processing techniques and spin relaxation theory. In the concluding chapter, a survey of the major multipulse and multidimensional NMR techniques is given, including selective excitation, correlation spectroscopies and NMR imaging. Nuclear Magnetic Resonance: Concepts and Methods will be invaluable to graduate and undergraduate students, giving a clear understanding of the physical and mathematical background which underlies the many applications of this powerful and sophisticated technique. It will also be of great interest to more experienced researchers in the many fields where NMR spectroscopy is now routinely used.

Nuclear quadrupole resonance (NQR) a highly promising new technique for bulk explosives detection: relatively inexpensive, more compact than NMR, but with considerable selectivity. Since the NQR frequency is insensitive to long-range variations in composition, mixing explosives with other materials, such as the plasticizers in plastic explosives, makes no difference. The NQR signal strength varies linearly with the amount of explosive, and is independent of its distribution within the volume monitored. NQR spots explosive types in configurations missed by the X-ray imaging method.

But if NQR is so good, why it is not used everywhere? Its main limitation is the low signal-to-noise ratio, particularly with the radio-frequency interference that exists in a field environment, NQR polarization being much weaker than that from an external magnetic field. The distinctive signatures are there, but are difficult to extract from the noise. In addition, the high selectivity is partly a disadvantage, as it is hard to build a multichannel system necessary to cover a wide range of target substances. Moreover, substances fully screened by metallic enclosures, etc. are difficult to detect. A workshop was held at St Petersburg in July 2008 in an attempt to solve these problems and make NQR the universal technique for the detection of bombs regardless of type. This book presents the essentials of the papers given there.

This volume presents pedagogical content to understand theoretical and practical aspects of diagnostic imaging techniques. It provides insights to current practices, and also discusses specific practical features like radiation exposure, radiation sensitivity, signal penetration, tissue interaction, and signal confinement with reference to individual imaging techniques. It also covers relatively less common imaging methods in addition to the established ones. It serves as a reference for researchers and students working in the field of medical, biomedical science, physics, and instrumentation. Key Features * Focusses on the clinical applications while ensuring a steady understanding of the underlying science * Follows a bottom-up approach to cover the theory, calculations, and modalities to aid students and researchers in biomedical imaging, radiology and instrumentation * Covers unique concepts of nanoparticle applications along with ethical issues in medical imaging

This text is aimed at people who have some familiarity with high-resolution NMR and who wish to deepen their understanding of how NMR experiments actually 'work'. This revised and updated edition takes the same approach as the highly-acclaimed first edition. The text concentrates on the description of commonly-used experiments and explains in detail the theory behind how such experiments work. The quantum mechanical tools needed to analyse pulse sequences are introduced set by step, but the approach is relatively informal with the emphasis on obtaining a good understanding of how the experiments actually work. The use of two-colour printing and a new larger format improves the readability of the text. In addition, a number of new topics have been introduced:

How product operators can be extended to describe experiments in AX2 and AX3 spin systems, thus making it possible to discuss the important APT, INEPT and DEPT experiments often used in carbon-13 NMR.Spin system analysis i.e. how shifts and couplings can be extracted from strongly-coupled (second-order) spectra.How the presence of chemically equivalent spins leads to spectral features which are somewhat unusual and possibly misleading, even at high magnetic fields.A discussion of chemical exchange effects has been introduced in order to help with the explanation of transverse relaxation.The double-quantum spectroscopy of a three-spin system is now considered in more detail.

Dynamics of Solutions and Fluid Mixtures by NMR Edited by Jean-Jacques Delpuech Universite Henri Poincare Nancy I, France One of the most outstanding contributions of NMR to chemistry concerns the information which can be obtained at the molecular level as a result of the time-dependence of NMR spectra. The importance of this information is well illustrated by the large number of applications which have resulted from research in this field. To date, however, both the theory and its applications have only been available in widely scattered articles in the literature. Dynamics of Solutions and Fluid Mixtures by NMR is the first single volume giving a comprehensive coverage of time-dependent effects in NMR, and of the information which can be obtained by investigation of these phenomena. The ten chapters, all written by acknowledged experts in their respective fields, are arranged in a logical progression. The first three chapters give an overview of NMR spectroscopy and the fundamental aspects of molecular dynamics. Topics covered in later chapters include specific relaxation mechanisms, the use of field gradients in the study of translational diffusion, and applications of the technique. Dynamics of Solutions and Fluid Mixtures by NMR provides a timely and comprehensive overview of time-dependent phenomena in NMR. It will be of great interest to analytical chemists and biochemists, and to researchers and students working specifically in the fields of applications covered in the volume.

During the last few years, routine applications of NMR techniques have been further developed. Spectrometers of the latest generation offer new types of experiments, such as spinlock and inverse-detected methods. In this third, revised and expanded edition, new methodology is introduced and incorporated into new exercises. In addition, a new chapter has been introduced which demonstrates the fully detailed interpretation of two typical examples.

This book is about pulse nuclear magnetic resonance (NMR), with its techniques, the information to be obtained, and practical advice on performing experiments. The emphasis is on the motivation and physical ideas underlying NMR experiments and the actual techniques, including the hardware used. The level is generally suitable for those to whom pulse NMR is a new technique, be they students in chemistry or physics on the one hand and research workers in biology, geology, or agriculture, on the other. The book can be used for a senior or first year graduate course where it could supplement the standard NMR texts.

This is the second of two books about African-American female chemists. The first book (African-American Women Chemists, 2011) focused on the early pioneers-women chemists from the Civil War to the Civil Rights Act. African American Women Chemists in the Modern Era focuses on contemporary women who have benefited from the Civil Rights Act and are now working as chemists or chemical engineers. This book was produced by taking the oral history of women who are leaders in their field and who wanted to tell the world how they suceeded. It features eighteen amazing women in this book and each of them has a claim to fame, despite hiding in plain sight. These women reveal the history of their lives from youth to adult. Overall, Jeannette Brown aims to inspire women and minorities to pursue careers in the sciences, as evidenced by the successful career paths of the women that came before them.

Clear, accessible coverage of modern NMR spectroscopy—for students and professionals in many fields of science

Nuclear magnetic resonance (NMR) spectroscopy has made quantum leaps in the last decade, becoming a staple tool in such divergent fields as chemistry, physics, materials science, biology, and medicine. That is why it is essential that scientists working in these areas be fully conversant with current NMR theory and practice.

This down-to-basics text offers a comprehensive, up-to-date treatment of the fundamentals of NMR spectroscopy. Using a straightforward approach that develops all concepts from a rudimentary level without using heavy mathematics, it gives readers the knowledge they need to solve any molecular structure problem from a complete set of NMR data. Topics are illustrated throughout with hundreds of figures and actual spectra. Chapter-end summaries and review problems with answers are included to help reinforce and test understanding of key material.

From NMR studies of biologically important molecules to magnetic resonance imaging, this book serves as an excellent all-around primer on NMR spectroscopic analysis.

"Introduction to Solid State NMR Spectroscopy" is written for undergraduate and graduate students of chemistry, either taking a course in advanced or solid-state nuclear magnetic resonance spectroscopy or undertaking research projects where solid-state NMR is likely to be a major investigative technique. It will also serve as a practical introduction in industry, where the techniques can provide new or complementary information to supplement other investigative techniques.

By covering solid-state NMR spectroscopy in a clear, straightforward and approachable way with detailed descriptions of the major solid-state NMR experiments focussing on what the experiments do and what they tell the researcher, this book will serve as an ideal introduction to the subject. These descriptions are backed up by separate mathematical explanations for those who wish to gain a more sophisticated quantitative understanding of the phenomena. With additional coverage of the practical implementation of solid-state NMR experiments integrated into the discussion, this book will be essential reading for all those using, or about to use, solid-state NMR spectroscopy.

Dr Melinda Duer is a senior lecturer in the Department of Chemistry at the University of Cambridge, Cambridge, UK.

Keeping mathematics to a minimum, this book introduces nuclear properties, nuclear screening, chemical shift, spin-spin coupling, and relaxation. It is one of the few books that provides the student with the physical background to NMR spectroscopy from the point of view of the whole of the periodic table rather than concentrating on the narrow applications of 1H and 13C NMR spectroscopy. Aids to structure determination, such as decoupling, the nuclear Overhauser effect, INEPT, DEPT, and special editing, and two dimensional NMR spectroscopy are discussed in detail with examples, including the complete assignment of the 1H and 13C NMR spectra of D-amygdain. The authors examine the requirements of a modern spectrometer and the effects of pulses and discuss the effects of dynamic processes as a function of temperature or pressure on NMR spectra. The book concludes with chapters on some of the applications of NMR spectroscopy to medical and non-medical imaging techniques and solid state chemistry of both I = F1/2 and I > F1/2 nuclei. Examples and problems, mainly from the recent inorganic/organometallic chemistry literature support the text throughout. Brief answers to all the problems are provided in the text with full answers at the end of the book.

Characterisation Methods in Inorganic Chemistry provides a fresh alternative to the existing theoretical and descriptive inorganic chemistry texts by adopting a techniques-based approach and providing problem-solving opportunities to show how analytical methods are used to help us characterise inorganic compounds. The text covers the full range of analytical techniques employed by inorganic chemists, emphasizing those in most frequent use: NMR, diffraction, UV-Vis spectroscopy, and IR. The additional coverage on other techniques allows readers to study these less widely used methods when relevant to their specific course material. Each chapter follows a clear, structured format, which begins with a brief introduction to the technique and basic theory behind it before moving on to data collection and analysis, typical data and interpretation, with numerous worked examples, self- tests and problems.

The combination of two leading imaging techniques - magnetic resonance imaging and positron emission tomography - is poised to have a large impact and has recently been a driver of research and clinical applications. The hybrid instrument is capable of acquiring both datasets simultaneously and this affords a number of advantages ranging from the obvious, two datasets acquired in the time required for one, through to novel applications. This book describes the basics of MRI and PET and then the technical issues and advantages involved in bringing together the two techniques. Novel applications in preclinical settings, human imaging and tracers are described. The book is for students and scientists entering the field of MR-PET with an MRI background but lacking PET or vice versa. It provides practical details from experts working in the area.

"Spin Dynamics: Basics of Nuclear Magnetic Resonance, Second Edition" is a comprehensive and modern introduction which focuses on those essential principles and concepts needed for a thorough understanding of the subject, rather than the practical aspects. The quantum theory of nuclear magnets is presented within a strong physical framework, supported by figures.

The book assumes only a basic knowledge of complex numbers and matrices, and provides the reader with numerous worked examples and exercises to encourage understanding. With the explicit aim of carefully developing the subject from the beginning, the text starts with coverage of quarks and nucleons and progresses through to a detailed explanation of several important NMR experiments, including NMR imaging, COSY, NOESY and TROSY.

Completely revised and updated, the Second Edition features new material on the properties and distributions of isotopes, chemical shift anisotropy and quadrupolar interactions, Pake patterns, spin echoes, slice selection in NMR imaging, and a complete new chapter on the NMR spectroscopy of quadrupolar nuclei. New appendices have been included on Euler angles, and coherence selection by field gradients. As in the first edition, all material is heavily supported by graphics, much of which is new to this edition.

Written for undergraduates and postgraduate students taking a first course in NMR spectroscopy and for those needing an up-to-date account of the subject, this multi-disciplinary book will appeal to chemical, physical, material, life, medical, earth and environmental scientists. The detailed physical insights will also make the book of interest for experienced spectroscopists and NMR researchers.

Praise from the reviews of the First Edition:

""This is an excellent book... that many teachers of NMR spectroscopy will cherish..." "It deserves to be a 'classic' among NMR spectroscopy texts".""" NMR IN BIOMEDICINE

""I strongly recommend this book to everyone...it is probably the best modern comprehensive description of the subject."" ANGEWANDTE CHEMIE, INTERNATIONAL EDITION

This book is for those familiar with solution-state NMR who are encountering solid-state NMR for the first time. It presents the current understanding and applications of solid-state NMR with a rigorous but readable approach, making it easy for someone who merely wishes to gain an overall impression of the subject without details. This dual requirement is met through careful construction of the material within each chapter.

The book is divided into two parts: "Fundamentals" and "Further Applications." The section on Fundamentals contains relatively long chapters that deal with the basic theory and practice of solid-state NMR. The essential differences and extra scope of solid-state NMR over solution-state is dealt with in an introductory chapter. The basic techniques that all chapters rely on are collected into a second chapter to avoid unnecessary repetition later. Remaining chapters in the "Fundamentals" part deal with the major areas of solid-state NMR which all solid-state NMR spectroscopists should know about. Each begins with an overview of the topic that puts the chapter in context.

The basic principles upon which the techniques in the chapter rely are explained in a separate section. Each of these chapters exemplifies the principles and techniques with the applications most commonly found in current practice.

The "Further Applications" section contains a series of shorter chapters which describe the NMR techniques used in other, more specific areas. The basic principles upon which these techniques rely will be expounded only if not already in the Fundamentals part.

Essential NMR gives scientists and engineers an easy and quick refresher on their NMR knowledge and skills. At the same time, this primer and review affords lecturers material to provide a deliver a framework of basic know-how covering all fields of NMR, i.e. NMR methodology and hardware, chemical analysis, 2D-spectroscopy, NMR imaging, flow NMR, and quality-control NMR. Concise explanatory text, with the key information, is enhanced a color illustration that graphically reinforces understanding. Rigorous derivations are avoided in favor of intuitive arguments. No other teaching-and-learning text addresses all the different aspects of NMR in such a comprehensive and concise fashion.
