The text combines theoretical discussion with concrete examples, making it suitable for analytical chemists, environmental chemists, organic chemists, medicinal chemists, university research chemists, and graduate and post-doctorate students.
The content of this volume has been added to "eMagRes" (formerly "Encyclopedia of Magnetic Resonance)" - the ultimate online resource for NMR and MRI. Over the past 20 years technical developments in superconducting magnet technology and instrumentation have increased the potential of NMR spectroscopy so that it is now possible to study a wide range of solid materials. In addition, one can probe the nuclear environments of many other additional atoms that possess the property of spin. In particular, it is possible to carry out NMR experiments on isotopes that have nuclear spin greater that 1/2 (i.e. quadrupolar nuclei). Since more that two-thirds of all NMR active isotopes are quadrupolar nuclei, applications of NMR spectroscopy with quadrupolar nuclei are increasing rapidly. The purpose of this handbook is to provide under a single cover the fundamental principles, techniques and applications of quadrupolar NMR as it pertains to solid materials. Each chapter has been prepared by an expert who has made significant contributions to out understanding and appreciation of the importance of NMR studies of quadrupolar nuclei in solids. The text is divided into three sections: The first provides the reader with the background necessary to appreciate the challenges in acquiring and interpreting NMR spectra of quadrupolar neclei in solids. The second presents cutting-edge techniques and methodology for employing these techniques to investigate quadrupolar nuclei in solids. The final section explores applications of solid-state NMR studies of solids ranging from investigations of dynamics, characterizations of biological samples, organic and inorganic materials, porous materials, glasses, catalysts, semiconductors and high-temperature superconductors. About "EMR Handbooks / eMagRes Handbooks" The "Encyclopedia of Magnetic Resonance "(up to 2012) and" eMagRes "(from 2013 onward) publish a wide range of online articles on all aspects of magnetic resonance in physics, chemistry, biology and medicine. The existence of this large number of articles, written by experts in various fields, is enabling the publication of a series of "EMR Handbooks / eMagRes Handbooks" on specific areas of NMR and MRI. The chapters of each of these handbooks will comprise a carefully chosen selection of articles from "eMagRes." In consultation with the "eMagRes" Editorial Board, the "EMR Handbooks / eMagRes Handbooks" are coherently planned in advance by specially-selected Editors, and new articles are written (together with updates of some already existing articles) to give appropriate complete coverage. The handbooks are intended to be of value and interest to research students, postdoctoral fellows and other researchers learning about the scientific area in question and undertaking relevant experiments, whether in academia or industry.

THE PRINCIPLES, APPLICATIONS, AND TRENDS OF A KEY TOOL IN FOOD SCIENCE Maximizing food potential has become one of the priorities of the food industry and near-infrared spectroscopy (NIRS) is fast becoming a key "ingredient" in achieving that goal. Taking its place among other proven spectroscopic tools, near-infrared spectroscopy facilitates, for example, quality measurements made early in the production when fresh products are still edible, helping to determine whether the product goes to fresh market or to processing and thereby minimizing waste. Near-Infrared Spectroscopy in Food Science and Technology is one of the few available resources that applies this valuable technique specifically to the food science and technology industries. Written by authors with extensive expertise in NIRS and food science, this comprehensive resource provides an introduction to and overview of the technical aspects of NIRS, including: Basic principles of near-infrared spectroscopy Characteristics of the NIR spectra Instrumentation Sampling techniques Chemometrics Stressing the practical application of near-infrared technology, the book details the method's use in four key areas of food science and technology: agricultural and marine products, foodstuffs and processed foods, engineering and process monitoring, and food safety and disease diagnosis. Nearly encyclopedic in its coverage, Near-Infrared Spectroscopy in Food Science and Technology will prove a valuable guide for food science professionals as well as scientists and engineers in a wide range of related fields.
This issue of Clinics in Laboratory Medicine, Guest Edited by Nigel Clarke, MD, and Andrew Hoofnagle, MD, will focus on Mass Spectrometry, with topics including: Proteins; Peptides; Small Molecules: Toxicology; Small Molecules: Diagnostics; and Regulatory Considerations.
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. Also available: Instructors Guide and Solutions Manual to Organic Structures from 2D NMR Spectra

With the ever increasing number of samples to be assayed in
agronomical laboratories and servicing stations, fertilizer and
food industries, sugar factories, water treatment plants,
biomedical laboratories, drug quality control, and environmental
research, the interest for automated chemical analysis has been
increasing. In this context, flow analysis is very attractive, as
they the flow-based procedures are characterized by enhanced
analytical figures of merit. Moreover, the flow analysers do not
usually require sophisticated and expensive instrumentation, are
amenable to full automation and to miniaturization, and are well
suited for in situ analyses. The tendency to carry out traditional
methods of analysis in the flow analyser has becoming more
pronounced, especially in relation to large-scale routine analyses.
The technology of solution handling has become more and more
improved, leading to enhanced strategies for chemical assays.
Consequently, different modalities of flow analysis (e.g. SFA, FIA,
SIA) have been conceived, developed and applied to solve real
problems. Most of the flow-based analytical procedures presently in
use, however, do not exploit the full potential of flow analysis.
The main object of the book is then to provide a scientific basis
and to familiarise a wide community of researchers, students,
technicians, etc with the uses of flow analysis. Emphasis is given
to spectrophotometric and luminometric detection, in relation to
agronomical, geological, industrial, pharmaceutical and
environmental applications. The book includes historical and
theoretical aspects, recent achievements in instrumentation,
guidelines for methodology implementation, and applications. It
serves also as an applications-oriented text book.

New topics include sample profiling, sample preparation, sustainable green chemistry, 2D chromatography, miniaturization/nano-LC, HILIC, and more.
Designed to sit alongside more conventional established condensed matter physics textbooks, this compact volume offers a concise presentation of the principles of solid state theory, ideal for advanced students and researchers requiring an overview or a quick refresher on a specific topic. The book starts from the one-electron theory of solid state physics, moving through electron-electron interaction and many-body approximation schemes, to lattice oscillations and their interactions with electrons. Subsequent chapters discuss transport theory and optical properties, phase transitions and some properties of low-dimensional semiconductors. This extensively expanded second edition includes new material on adiabatic perturbation theory, kinetic coefficients, the Nyquist theorem, Bose condensation, and the field-theoretical approach to non-relativistic quantum electrodynamics. Throughout the text, mathematical proofs are often only sketched, and the final chapter of the book reviews some of the key concepts and formulae used in theoretical physics. Aimed primarily at graduate and advanced undergraduate students taking courses on condensed matter theory, the book serves as a study guide to reinforce concepts learned through conventional solid state texts. Researchers and lecturers will also find it a useful resource as a concise set of notes on fundamental topics.

Much of what we know about atoms, molecules, and the nature of
matter has been obtained using spectroscopy over the last one
hundred years or so. In this book we have collected together twenty
chapters by eminent scientists from around the world to describe
their work at the cutting edge of molecular spectroscopy. These
chapters describe new methodology and applications, instrumental
developments, and theory which is taking spectroscopy into new
frontiers. The range of topics is broad. Lasers are utilized in
much of the research, but their applications range from
sub-femtosecond spectroscopy to the study of viruses and also to
the investigation of art and archeological artifacts. Three
chapters discuss work on biological systems and three others
represent laser physics. The recent advances in cavity ringdown
spectroscopy (CRDS), surface enhanced Raman spectroscopy (SERS),
two-dimensional correlation spectroscopy (2D-COS), and microwave
techniques are all covered. Chapters on electronic excited states,
molecular dynamics, symmetry applications, and neutron scattering
are also included and demonstrate the wide utility of spectroscopic
techniques.
This book is designed to be a central text for young graduate
students interested in mass spectrometry as it relates to study of
protein structure and function as well as proteomics.
The unique compendium presents special principles and techniques of spectroscopic measurements that are used in semiconductor manufacturing.Since industrial applications of spectroscopy are significantly different from those traditionally used in scientific laboratories, the design concepts and characteristics of industrial spectroscopic devices may vary significantly from conventional systems.

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.
The detection of hidden explosives has become an issue of utmost
importance in recent years. While terrorism is not new to the

issue of detection of explosives and have generated a great demand
for rapid, sensitive and reliable methods for detecting hidden
explosives. Counterterrorist Detection Techniques of Explosives
covers recent advances in this area of research including vapor and
trace detection techniques (chemiluminescence, mass spectrometry,
ion mobility spectrometry, electrochemical methods and
micromechanical sensors, such as microcantilevers) and bulk
detection techniques (neutron techniques, nuclear quadrupole
resonance, x-ray diffraction imaging, millimeter-wave imaging,
terahertz imaging and laser techniques). This book will be of
interest to any scientists involved in the design and application
of security screening technologies including new sensors and
detecting devices which will prevent the smuggling of bombs and
explosives. |
