Ideas Of Quantum Chemistry

Ideas of Quantum Chemistry shows how quantum mechanics is applied to chemistry to give it a theoretical foundation. The structure of the book (a TREE-form) emphasizes the logical relationships between various topics, facts and methods. It shows the reader which parts of the text are needed for understanding specific aspects of the subject matter. Interspersed throughout the text are short biographies of key scientists and their contributions to the development of the field.Ideas of Quantum Chemistry has both textbook and reference work aspects. Like a textbook, the material is organized into digestable sections with each chapter following the same structure. It answers frequently asked questions and highlights the most important conclusions and the essential mathematical formulae in the text. In its reference aspects, it has a broader range than traditional quantum chemistry books and reviews virtually all of the pertinent literature. It is useful both for beginners as well as specialists in advanced topics of quantum chemistry. The book is supplemented by an appendix on the Internet. * Presents the widest range of quantum chemical problems covered in one book * Unique structure allows material to be tailored to the specific needs of the reader * Informal language facilitates the understanding of difficult topics

This graduate-level text explains the modern in-depth approaches to the calculation of electronic structure and the properties of molecules. Largely self-contained, it features more than 150 exercises. 1989 edition.

Ideas of Quantum Chemistry, Volume One: From Quantum Physics to Chemistry shows how quantum mechanics is applied to molecular sciences to provide a theoretical foundation. Organized into digestible sections and written in an accessible style, it answers questions, highlighting the most important conclusions and essential mathematical formulae. Beginning with an introduction to the magic of quantum mechanics, the book goes on to review such key topics as the Schrödinger Equation, exact solutions, and fundamental approximate methods. The crucial concept of molecular shape is then discussed, followed by the motion of nuclei and the orbital model of electronic structure. This updated volume covers the latest developments in the field and can be used either on its own as a detailed introduction to quantum chemistry or in combination with Volume Two to give a complete overview of the field. Provides fully updated coverage on an extensive range of both foundational and complex topics Uses an innovative structure to emphasize relationships between topics and help readers tailor their own path through the book Includes new sections on Time-Energy Uncertainty and Virial Theorem

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.

Classic undergraduate text explores wave functions for the hydrogen atom, perturbation theory, the Pauli exclusion principle, and the structure of simple and complex molecules. Numerous tables and figures.

Some knowledge of the principles of quantum mechanics and how they are applied to theoretical chemistry, it is generally agreed, should be part of the education of all chemists. This instruction in quantum chemistry is either added to the more traditional topics of physical chemistry or given separately; at Syracuse University it forms the third semester of the physical chemistry sequence. While a wide variety of textbooks and monographs on the subject of quantum chemistry exists, the author of the present text found that none of them was satisfactory for his purposes, i. e. , none fit his ideas of what subjects should be discussed and in what way. This book is presented with the hope that others with similar experiences will agree with him and endorse his conclusions. The undergraduate student to whom our attentions are directed is a chemistry major, but probably will not go on to graduate school in physical chemistry. He may take several more chemistry courses as an undergraduate and then seek a position in industry, or perhaps he will do graduate work in organic or inorganic chemistry. (Of course, one never stops hoping that, as a result of this first course, he will decide to learn more quantum chem istry.

Experimental Quantum Chemistry is a comprehensive account of experimental quantum chemistry and covers topics ranging from basic quantum theory to atoms and ions, photons, electrons, and positrons. Nuclei, molecules, and free radicals are also discussed. This volume is comprised of eight chapters and begins with an overview of the basic experiments and ideas leading to the development of quantum theory, with special emphasis on the problems of chemistry. The main properties of electromagnetic radiation are then considered, along with the most important relations of electrons and positrons in chemistry; the quantum theory of isolated atoms and ions; the structure of nuclei and the main applications to organic chemistry; and the chemical structure and reactivity of molecules. The theoretical and experimental aspects of interpreting free radical structures on the basis of the molecular orbital and valence bond theories are also explored. The final chapter is devoted to the chemistry of the organic solid state, paying particular attention to the structure and molecular mobilities of organic solids, collective crystal states (excitons, phonons, and polaritons), energy transfer processes, and reactions in the solid state. This book should be of interest to physicists and organic chemists.

Ideas of Quantum Chemistry, Volume Two: Interactions highlights the motions and systems in quantum chemistry and the models and tools used to assess them, thus giving detailed insights into the behaviors underlying quantum chemistry. Using an innovative structure to show the logical relationships between different topics, systems and methods, it answers questions and emphasizes knowledge using practical examples. Beginning with a review of the orbital model of electronic motion in periodic systems, the book goes on to explore the correlation of electronic motions, density functional theory (DFT), electric and magnetic fields, intermolecular interactions, chemical reactions and information processing. This third release has been updated and revised to cover the latest developments in the field. It can be used on its own as a guide to key interactions and tools or in combination with Volume Two to give a complete overview of the field. Features a practical range of quantum chemical problems throughout to support further understanding of interactions Uses informal language and unique structure to make complex topics accessible Includes new sections on Electronic Currents, Electron Autocorrelation and Spintronics
