## Basic principles and techniques of molecular quantum mechanics

**Author**: Ralph E. Christoffersen**Publisher:**Springer Verlag**ISBN:**9780387967592**Category:**Science**Page:**686**View:**8639

The primary purpose of the book is to provide a detailed understanding of the principles and techniques of molecular quantum mechanics. It is intended as both a classroom and reference textbook for graduate students, advanced undergraduate students, and researchers with diverse backgrounds. It provides sufficient material to allow the student to proceed from a study of basic principles to understanding contemporary research in molecular quantum mechanics. Many features of this book differentiate it from other available books. First, rigor and depth of understanding were not sacrificed simply for the purpose of brevity. Since the text also serves as a reference book, an extensive bibliography to literature articles and other sources is also included. The book presents a comprehensive set of topics, many of which are omitted in comparable textbooks.

## Computational Chemistry

*Introduction to the Theory and Applications of Molecular and Quantum Mechanics*

**Author**: Errol G. Lewars**Publisher:**Springer**ISBN:**3319309161**Category:**Science**Page:**728**View:**2092

This is the third edition of the successful text-reference book that covers computational chemistry. It features changes to the presentation of key concepts and includes revised and new material with several expanded exercises at various levels such as 'harder questions' for those ready to be tested in greater depth - this aspect is absent from other textbooks in the field. Although introductory and assuming no prior knowledge of computational chemistry, it covers the essential aspects of the subject. There are several introductory textbooks on computational chemistry; this one is (as in its previous editions) a unique textbook in the field with copious exercises (and questions) and solutions with discussions. Noteworthy is the fact that it is the only book at the introductory level that shows in detail yet clearly how matrices are used in one important aspect of computational chemistry. It also serves as an essential guide for researchers, and as a reference book. div“/div>

## Advanced Molecular Quantum Mechanics

*An Introduction to Relativistic Quantum Mechanics and the Quantum Theory of Radiation*

**Author**: R. Moss**Publisher:**Springer Science & Business Media**ISBN:**9400956886**Category:**Science**Page:**300**View:**7992

This book is primarily intended for graduate chemists and chemical physicists. Indeed, it is based on a graduate course that I give in the Chemistry Depart ment of Southampton University. Nowadays undergraduate chemistry courses usually include an introduction to quantum mechanics with particular reference to molecular properties and there are a number of excellent textbooks aimed specifically at undergraduate chemists. In valence theory and molecular spectroscopy physical concepts are often encountered that are normally taken on trust. For example, electron spin and the anomalous magnetic moment of the electron are usually accepted as postulates, although they are well understood by physicists. In addition, the advent of new techniques has led to experimental situations that can only be accounted for adequately by relatively sophisticated physical theory. Relativis tic corrections to molecular orbital energies are needed to explain X-ray photo electron spectra, while the use oflasers can give rise to multiphoton transitions, which are not easy to understand using the classical theory of radiation. Of course, the relevant equations may be extracted from the literature, but, if the underlying physics is not understood, this is a practice that is at best dissatisfy ing and at worst dangerous. One instance where great care must be taken is in the use of spectroscopically determined parameters to test the accuracy of elec tronic wave functions.

## Relativistic Quantum Chemistry

*The Fundamental Theory of Molecular Science*

**Author**: Markus Reiher,Alexander Wolf**Publisher:**John Wiley & Sons**ISBN:**352766758X**Category:**Science**Page:**750**View:**1859

Einstein proposed his theory of special relativity in 1905. For a long time it was believed that this theory has no significant impact on chemistry. This view changed in the 1970s when it was realized that (nonrelativistic) Schr?dinger quantum mechanics yields results on molecular properties that depart significantly from experimental results. Especially when heavy elements are involved, these quantitative deviations can be so large that qualitative chemical reasoning and understanding is affected. For this to grasp the appropriate many-electron theory has rapidly evolved. Nowadays relativistic approaches are routinely implemented and applied in standard quantum chemical software packages. As it is essential for chemists and physicists to understand relativistic effects in molecules, the first edition of "Relativistic Quantum Chemistry - The fundamental Theory of Molecular Science" had set out to provide a concise, comprehensive, and complete presentation of this theory. This second edition expands on some of the latest developments in this fascinating field. The text retains its clear and consistent style, allowing for a readily accessible overview of the complex topic. It is also self-contained, building on the fundamental equations and providing the mathematical background necessary. While some parts of the text have been restructured for the sake of clarity a significant amount of new content has also been added. This includes, for example, an in-depth discussion of the Brown-Ravenhall disease, of spin in current-density functional theory, and of exact two-component methods and its local variants. A strength of the first edition of this textbook was its list of almost 1000 references to the original research literature, which has made it a valuable reference also for experts in the field. In the second edition, more than 100 additional key references have been added - most of them considering the recent developments in the field. Thus, the book is a must-have for everyone entering the field, as well as for experienced researchers searching for a consistent review.
