This book provides non-specialists with a basic understanding ofthe underlying concepts of quantum chemistry. It is both a text for second or third-year undergraduates and a reference for researchers who need a quick introduction or refresher. All chemists and many biochemists, materials scientists, engineers, and physicists routinely user spectroscopic measurements and electronic structure computations in their work. The emphasis of Quantum Chemistry on explaining ideas rather than enumerating facts or presenting procedural details makes this an excellent foundation text/reference. The keystone is laid in the first two chapters which deal with molecular symmetry and the postulates of quantum mechanics, respectively. Symmetry is woven through the narrative of the next three chapters dealing with simple models of translational, rotational, and vibrational motion that underlie molecular spectroscopy and statistical thermodynamics. The next two chapters deal with the electronic structure of the hydrogen atom and hydrogen molecule ion, respectively. Having been armed with a basic knowledge of these prototypical systems, the reader is ready to learn, in the next chapter, the fundamental ideas used to deal with the complexities of many-electron atoms and molecules. These somewhat abstract ideas are illustrated with the venerable Huckel model of planar hydrocarbons in the penultimate chapter. The book concludes with an explanation of the bare minimum of technical choices that must be made to do meaningful electronic structure computations using quantum chemistry software packages.

A comprehensive, practical examination of the basic principles andinner mechanics of matter . . . Moving from pure principles to real applications, the QuantumChemistry Workbook is a step-by-step study guide to the innerworkings of nature's fundamental systems: free atoms, smallmolecules, polymers, and crystals. Beginning with a short, clearsummary of the basics of quantum mechanics, the Workbook offers achapter-by-chapter exposition in a highly interactive exercise andquestion format that allows readers to work through the mainconcepts discussed. Not simply a conventional workbook, the QuantumChemistry Workbook encourages discovery and original reflection,allowing users, through its rigorous give and take, to discover theintriguing connections hidden within the science. The Workbookincludes: * A comparative overview of how basic concepts and principlesactually work in free atoms, small molecules, polymers, andcrystals * A practical look at the approximation level of a one-electrontype * A complete examination of momentum space, with numerousconceptual illustrations * Atomic units used throughout An essential companion to any textbook on chemistry and physics,the Quantum Chemistry Workbook is ideal for professors interestedin giving students a firm grasp of the working basics of thescience. For students and professionals interested in pursuing thefundamentals of quantum chemistry on their own, the Workbook is anincomparable introduction and study tool.

This textbook introduces the reader to quantum theory and quantum chemistry. The textbook is meant for 2nd – 3rd year bachelor students of chemistry or physics, but also for students of related disciplines like materials science, pharmacy, and bioinformatics. At first, quantum theory is introduced, starting with experimental results that made it inevitable to go beyond classical physics. Subsequently, the Schrödinger equation is discussed in some detail. Some few examples for which the Schrödinger equation can be solved exactly are treated with special emphasis on relating the results to real systems and interpreting the mathematical results in terms of experimental observations. Ultimately, approximate methods are presented that are used when applying quantum theory in the field of quantum chemistry for the study of real systems like atoms, molecules, and crystals. Both the foundations for the different methods and a broader range of examples of their applications are presented. The textbook assumes no prior knowledge in quantum theory. Moreover, special emphasis is put on interpreting the mathematical results and less on an exact mathematical derivations of those. Finally, each chapter closes with a number of questions and exercises that help in focusing on the main results of the chapter. Many of the exercises include answers.

Advanced graduate-level text looks at symmetry, rotations, and angular momentum addition; occupation number representations; and scattering theory. Uses concepts to develop basic theories of chemical reaction rates. Problems and answers.
