Written chemical formulas, such as C2H6O, can tell us the constituent atoms a molecule contains but they cannot differentiate between the possible geometrical arrangements (isomers) of these models. Yet the chemical properties of different isomers can vary hugely. Therefore, to understand the world of chemistry we need to ask what kind of isomers can be produced from a given atomic composition, how are isomers converted into each other, how do they decompose into smaller pieces, and how can they be made from smaller pieces? The answers to these questions will help us to discover new chemistry and new molecules. A potential energy surface (PES) describes a system, such as a molecule, based on geometrical parameters. The mathematical properties of the PES can be used to calculate probable isomer structures as well as how they are formed and how they might behave. Exploration on Quantum Chemical Potential Energy Surfaces focuses on the PES search based on quantum chemical calculations. It describes how to explore the chemical world on PES, discusses fundamental methods and specific techniques developed for efficient exploration on PES, and demonstrates several examples of the PES search for chemical structures and reaction routes.

What Arieh Warshel and fellow 2013 Nobel laureates Michael Levitt and Martin Karplus achieved - beginning in the late 1960s and early 1970s when computers were still very primitive - was the creation of methods and programs that describe the action of biological molecules by 'multiscale models'. In this book, Warshel describes this fascinating, half-century journey to the apex of science.From Kibbutz Fishponds to The Nobel Prize is as much an autobiography as an advocacy for the emerging field of computational science. We follow Warshel through pivotal moments of his life, from his formative years in war-torn Israel in an idealistic kibbutz that did not encourage academic education; to his time in the army and his move to the Technion where he started in his obsession of understanding the catalytic power of enzymes; to his eventual scientific career which took him to the Weizmann Institute, Harvard University, Medical Research Council, and finally University of Southern California. We read about his unique contributions to the elucidation of the molecular basis of biological functions, which are combined with instructive stories about his persistence in advancing ideas that contradict the current dogma, and the nature of his scientific struggle for recognition, both personal and for the field to which he devoted his life. This is, in so many ways, more than just a memoir: it is a profoundly inspirational tale of one man's odyssey from a kibbutz that did not allow him to go to a university to the pinnacle of the scientific world, highlighting that the correct mixture of persistence, talent and luck can lead to a Nobel Prize.

Quantum mechanics - central not only to physics, but also to chemistry, materials science, and other fields - is notoriously abstract and difficult. Essential Quantum Mechanics is a uniquely concise and explanatory book that fills the gap between introductory and advanced courses, between popularizations and technical treatises. By focusing on the fundamental structure, concepts, and methods of quantum mechanics, this introductory yet sophisticated work emphasizes both physical and mathematical understanding. A modern perspective is adopted throughout - the goal, in part, being to gain entry into the world of 'real' quantum mechanics, as used by practicing scientists. With over 60 original problems, Essential Quantum Mechanics is suitable as either a text or a reference. It will be invaluable to physics students as well as chemists, electrical engineers, philosophers, and others whose work is impacted by quantum mechanics, or who simply wish to better understand this fascinating subject.

The field of relativistic electronic structure theory is generally not part of theoretical chemistry education, and is therefore not covered in most quantum chemistry textbooks. This is due to the fact that only in the last two decades have we learned about the importance of relativistic effects in the chemistry of heavy and superheavy elements. Developments in computer hardware together with sophisticated computer algorithms make it now possible to perform four-component relativistic calculations for larger molecules. Two-component and scalar all-electron relativistic schemes are also becoming part of standard ab-initio and density functional program packages for molecules and the solid state. The second volume of this two-part book series is therefore devoted to applications in this area of quantum chemistry and physics of atoms, molecules and the solid state. Part 1 was devoted to fundamental aspects of relativistic electronic structure theory whereas Part 2 covers more of the applications side. This volume opens with a section on the Chemistry of the Superheavy Elements and contains chapters dealing with Accurate Relativistic Fock-Space Calculations for Many-Electron Atoms, Accurate Relativistic Calculations Including QED, Parity-Violation Effects in Molecules, Accurate Determination of Electric Field Gradients for Heavy Atoms and Molecules, Two-Component Relativistic Effective Core Potential Calculations for Molecules, Relativistic Ab-Initio Model Potential Calculations for Molecules and Embedded Clusters, Relativistic Pseudopotential Calculations for Electronic Excited States, Relativistic Effects on NMR Chemical Shifts, Relativistic Density Functional Calculations on Small Molecules, Quantum Chemistry with the Douglas-Kroll-Hess Approach to Relativistic Density Functional Theory, and Relativistic Solid State Calculations.
- Comprehensive publication which focuses on new developments in relativistic quantum electronic structure theory
- Many leaders from the field of theoretical chemistry have contributed to the TCC series
- Will no doubt become a standard text for scientists in this field.

This book originated out of a desire to combine topics on vibrational absorption, Raman scattering, vibrational circular dichroism (VCD) and Raman optical activity (VROA) into one source. The theoretical details of these processes are presented in ten different chapters. Using dispersive and Fourier transform techniques, the instrumentation involved in these spectral measurements are given in three chapters. Major emphasis is placed on the newer techniques, i.e. VCD and VROA, with the conventional vibrational absorption and vibrational Raman scattering methods incorporated as natural parts of the newer methods.

Features of this book:

Comprehensive coverage of vibrational circular dichroism and vibrational Raman optical activity.

Coverage of theoretical and instrumental details.

A comprehensive survey of VCD and VROA applications is included, so that the reader can get an overview of theory, instrumentation and applications in one source.

The topics covered are of an advanced level, which makes this book invaluable for graduate students and practising scientists in vibrational spectroscopy.

This volume presents a variety of articles that encompass the broad scope of supramolecular chemistry. Reusch's chapter covers biological channel compounds, while the work of Hall and Kirkovits looks into their synthetic counterparts. Metal ion sensors, calixarenes and "crystal engineering" are described by pioneers in these fields. This work, whilst current and authoritative, shows us that much remains to be undertaken and understood. It is hoped that this volume will be of interest to those who wish to fill these gaps; scientists already in the field and those who may see extensions of their own work that will bring them into it.

This volume focuses on the use of quantum theory to understand and explain experiments in organic chemistry. High level ab initio calculations, when properly performed, are useful in making quantitative distinctions between various possible interpretations of structures, reactions and spectra. Chemical reasoning based on simpler quantum models is, however, essential to enumerating the likely possibilities. The simpler models also often suggest the type of wave function likely to be involved in ground and excited states at various points along reaction paths. This preliminary understanding is needed in order to select the appropriate higher level approach since most higher level models are designed to describe improvements to some reasonable zeroth order wave function. Consequently, most of the chapters in this volume begin with experimental facts and model functions and then progress to higher level theory only when quantitative results are required.In the first chapter, Zimmerman discusses a wide variety of thermal and photochemical reactions of organic molecules. Gronert discusses the use of ab initio calculations and experimental facts in deciphering the mechanism of -elimination reactions in the gas phase. Bettinger et al focus on carbene structures and reactions with comparison of the triplet and singlet states. Next, Hrovat and Borden discuss more general molecules with competitive triplet and singlet contenders for the ground state structure. Cave explains the difficulties and considerations involved with many of the methods and illustrates the difficulties by comparing with the UV spectra of short polyenes. Jordan et al discuss long-range electron transfer using model compounds and model Hamiltonians. Finally, Hiberty discusses the breathing orbital valence bond model as a different approach to introducing the crucial correlation that is known to be important in organic reactions.
