A foundation for quantitative perspectives and a framework for interpreting experimental observations.

Researchers in the life sciences who are unaware of the origins of the fundamental concepts and theoretical constructs in ligand-receptor energetics may fail to recognize the hidden assumptions and premises in their interpretations of observed phenomena. This book offers a detailed exposition of these fundamentals and of the treatment of multiple equilibria in successive steps of the binding of ligands to receptors. It also describes the calculations and meanings of energetic quantities for ligand-receptor complexes.

Ligand-Receptor Energetics is the only book on this topic that is both accessible to beginners and extremely useful for experienced investigators. It features numerous specific examples; tables of literature results; extensive, up-to-date thermodynamic data; graphical representations of ligand bonding concepts; and four helpful appendices. Topics covered include:

• Affinities —from site, stoichiometric, and ghost-site perspectives
• Facts and fantasies from graphical analyses
• Numerical evaluation of stoichiometric binding constants
• Affinity profiles
• Thermodynamic perspectives
• Forces of interaction
• Molecular scenarios.

This valuable supplementary text for students in all areas of the basic life sciences is also an excellent professional reference for researchers in biochemistry, molecular biology, physiology, biophysics, microbiology, neurobiology, immunology, pharmacology, endocrinology, and toxicology.

Beginning with a short, clear summary of the basics of quantum mechanics, the Workbook offers a chapter-by-chapter exposition in a highly interactive exercise and question format that allows readers to work through the main concepts discussed. Not simply a conventional workbook, the Quantum Chemistry Workbook encourages discovery and original reflection, allowing users, through its rigorous give and take, to discover the intriguing connections hidden within the science. The Workbook includes:

• A comparative overview of how basic concepts and principles actually work in free atoms, small molecules, polymers, and crystals
• A practical look at the approximation level of a one-electron type
• A complete examination of momentum space, with numerous conceptual illustrations
• Atomic units used throughout

An essential companion to any textbook on chemistry and physics, the Quantum Chemistry Workbook is ideal for professors interested in giving students a firm grasp of the working basics of the science. For students and professionals interested in pursuing the fundamentals of quantum chemistry on their own, the Workbook is an incomparable introduction and study tool.

Every serious student of chemistry should try to develop a `feel' for the way molecules behave - for the way they are put together and especially for the rules of engagement which operate when molecules meet and react. This primer describes how stereoelectronic effects control this behaviour. It is the only concise text on this topic at an undergraduate level. This is an important subject area and the comprehensive yet concise coverage in this book shows students how to build up a powerful but simple way of thinking about chemistry.

Winner of the PROSE Award for Chemistry & Physics 2010

Acknowledging the very best in professional and scholarly publishing, the annual PROSE Awards recognise publishers' and authors' commitment to pioneering works of research and for contributing to the conception, production, and design of landmark works in their fields. Judged by peer publishers, librarians, and medical professionals, Wiley are pleased to congratulate Professor Ian Fleming, winner of the PROSE Award in Chemistry and Physics for "Molecular Orbitals and Organic Chemical Reactions."

Molecular orbital theory is used by chemists to describe the arrangement of electrons in chemical structures. It is also a theory capable of giving some insight into the forces involved in the making and breaking of chemical bonds--the chemical reactions that are often the focus of an organic chemist's interest. Organic chemists with a serious interest in understanding and explaining their work usually express their ideas in molecular orbital terms, so much so that it is now an essential component of every organic chemist's skills to have some acquaintance with molecular orbital theory.

"Molecular Orbitals and Organic Chemical Reactions" is both a simplified account of molecular orbital theory and a review of its applications in organic chemistry; it provides a basic introduction to the subject and a wealth of illustrative examples. In this book molecular orbital theory is presented in a much simplified, and entirely non-mathematical language, accessible to every organic chemist, whether student or research worker, whether mathematically competent or not. Topics covered include:

- Molecular Orbital Theory

- Molecular Orbitals and the Structures of Organic Molecules

- Chemical Reactions -- How Far and How Fast

- Ionic Reactions -- Reactivity

- Ionic Reactions -- Stereochemistry

- Pericyclic Reactions

- Radical Reactions

- Photochemical Reactions

This expanded Reference Edition of "Molecular Orbitals and Organic Chemical Reactions" takes the content and the same non-mathematical approach of the Student Edition, and adds extensive extra subject coverage, detail and over 1500 references. The additional material adds a deeper understanding of the models used, and includes a broader range of applications and case studies. Providing a complete in-depth reference for a more advanced audience, this edition will find a place on the bookshelves of researchers and advanced students of organic, physical organic and computational chemistry.

The student edition of "Molecular Orbitals and Organic Chemical Reactions "presents molecular orbital theory in a simplified form, and offers an invaluable first textbook on this important subject for students of organic, physical organic and computational chemistry. Further information can be viewed here.

""These books are the result of years of work, which began as an attempt to write a second edition of my 1976 book Frontier Orbitals and Organic Chemical Reactions. I wanted to give a rather more thorough introduction to molecular orbitals, while maintaining my focus on the organic chemist who did not want a mathematical account, but still wanted to understand organic chemistry at a physical level. I'm delighted to win this prize, and hope a new generation of chemists will benefit from these books." - Professor Ian Fleming"

The Nature of the Chemical Bond provides a general treatment, essentially nonmathematical, of present (as of 1960) knowledge about the structure of molecules and crystals and the nature of the chemical bond. Among the new features in the third edition are a detailed resonating-valence-bond theory of electron-deficient substances, such as the boranes and ferrocene; a chemical theory of the electronic structure of metals and intermetallic compounds; a discussion of the role of the hydrogen bond in the structures of proteins and nucleic acids; the electroneutrality principle; and other new principles of molecular structure.

Almost 100 years have passed since Trautz and Lewis put forward their collision theory of molecular processes. Today, knowledge of molecular collisions forms a key part of predicting and understanding chemical reactions. This book begins by setting out the classical and quantum theories of atom-atom collisions. Experimentally observable aspects of the scattering processes; their relationship to reaction rate constants and the experimental methods used to determine them are described. The quantum mechanical theory of reactive scattering is presented and related to experimental observables. The role of lasers in the measurement and analysis of reactive molecular collisions is also discussed. Written with postgraduates and newcomers to the field in mind, mathematics is kept to a minimum, and readers are guided to appendices and further reading to gain a deeper understanding of the mathematics involved.

Im Jahr 1937 erschienen die ersten Lehrbucher des damals noch sehr jungen Fachgebiets der Quantenchemie, beide geschrieben von Hans Hellmann (1903-1938). Im Gegensatz zu anderen fruhen Werken zu diesem und nah verwandten Fachgebieten, wie den Buchern von Pauling & Wilson (1935) oder von Eyring, Walter & Kimball (1944), wurden Hellmanns Lehrbucher spater weder nachgedruckt noch neu aufgelegt. Beachtet man seine bedeutenden wissenschaftlichen Leistungen - erwahnt seien hier die Aufklarung der Natur der kovalenten chemischen Bindung (1933), das molekulare Virialtheorem (1933), das quantenmechanische Krafttheorem (1933, 1936/1937, heute als Hellmann-Feynman-Theorem bekannt), die Pseudopotentialmethode (1934) und die spater von Born und Huang erneut und weiter bearbeitete Theorie der diabatischen und adiabatischen Elementarreaktionen (1935) -, so kann dieser Sachverhalt nur unzureichend durch Hellmanns tragisches Schicksal erklart werden. Eine Neuauflage der deutschen Fassung von Hellmanns Lehrbuch ist daher mehr als wunschenswert.

Die Theoretische Chemie hat eine zweihundert Jahre alte Tradition in der Chemie. Zu Anfang des 19. Jahrhunderts, als die Chemie sich als eigenstandige Wissenschaft zu etablieren begann, erschienen ein- oder mehrbandige Werke zur Theoretischen Chemie. Das vorliegende Werk basiert auf einem Genealogie-Projekt des Autors, stellt gewissermassen ein Who is who der Theoretischen Chemie dar und beschreibt ihre Entwicklung in Deutschland in den letzten 200 Jahren.

There have been significant developments in the use of knowledge-based expert systems in chemistry since the first edition of this book was published in 2009. This new edition has been thoroughly revised and updated to reflect the advances. The underlying theme of the book is still the need for computer systems that work with uncertain or qualitative data to support decision-making based on reasoned judgements. With the continuing evolution of regulations for the assessment of chemical hazards, and changes in thinking about how scientific decisions should be made, that need is ever greater. Knowledge-based expert systems are well established in chemistry, especially in relation to toxicology, and they are used routinely to support regulatory submissions. The effectiveness and continued acceptance of computer prediction depends on our ability to assess the trustworthiness of predictions and the validity of the models on which they are based. Written by a pioneer in the field, this book provides an essential reference for anyone interested in the uses of artificial intelligence for decision making in chemistry.

Quantum tunnelling is one of the strangest phenomena in chemistry, where we see the wave nature of atoms acting in "impossible" ways. By letting molecules pass through the kinetic barrier instead of over it, this effect can lead to chemical reactions even close to the absolute zero, to atypical spectroscopic observations, to bizarre selectivity, or to colossal isotopic effects. Quantum mechanical tunnelling observations might be infrequent in chemistry, but it permeates through all its disciplines producing remarkable chemical outcomes. For that reason, the 21st century has seen a great increase in theoretical and experimental findings involving molecular tunnelling effects, as well as in novel techniques that permit their accurate predictions and analysis. Including experimental, computational and theoretical chapters, from the physical and organic to the biochemistry fields, from the applied to the academic arenas, this new book provides a broad and conceptual perspective on tunnelling reactions and how to study them. Quantum Tunnelling in Molecules is the obligatory stop for both the specialist and those new to this world.

This book explores chemical bonds, their intrinsic energies, and the corresponding dissociation energies which are relevant in reactivity problems. It offers the first book on conceptual quantum chemistry, a key area for understanding chemical principles and predicting chemical properties. It presents NBO mathematical algorithms embedded in a well-tested and widely used computer program (currently, NBO 5.9). While encouraging a "look under the hood" (Appendix A), this book mainly enables students to gain proficiency in using the NBO program to re-express complex wavefunctions in terms of intuitive chemical concepts and orbital imagery.

Dieses Buch behandelt die Computerapplikationen im Zeitraum 1970 bis 2000 in der Mitteldeutschen Chemieindustrie. Dabei wird die Wirkung von Algorithmen der Computerchemie in der Produktionssphare dargestellt. Zusatzlich zu diesen fachlich-mathematischen Darstellungen werden reportageartig Stimmungsbilder uber diese damals neue Disziplin der Chemie eingeblendet, also ein kulturhistorischer Background gegeben. Damit entsteht zugleich ein historischer Abriss der Chemieindustrie in Mitteldeutschland. Die Applikationen der Computerchemie bilden damals den Versuch der Modernisierung einer an sich im Althergebrachten verharrenden Chemie. Besonders die Einfuhrung der Fuzzy-Set-Theorie stellt jedoch die allein auf Machtausubung organisierten Leitungsstrukturen vor fast unloesbare Probleme. Die Breite der Applikationen von der Molekuldarstellung, der Datenbankrecherche, Fuzzy-Prozesskontrolle der Simulation der Karzinogenitat und des Sensorbaus und des Bioabbaus basiert auf einer geschickten multivariaten Verwendung der Algorithmen.

The three-dimensional aspects of molecular shape can be crucial to both properties and reactions. The Third Dimension explores the arrangements of atoms in molecules and in different types of solids. Initial chapters describe the common crystal structures and how they are related to close-packed arrangements of ions. Metallic, ionic, molecular and extended covalent crystals are covered; major types of crystal defects are also discussed. The book then introduces isomerism, and explores the stereochemical consequences of the tetrahedral carbon atom. Chirality is also investigated. The book concludes with a Case Study on Liquid Crystals, which describes structures, properties and applications. As visualisation in 3D is an important part of this book, the accompanying CD-ROMs provide video material, interactive questions and exercises using models to aid understanding of crystals, organic molecules and stereochemistry. All necessary programs are provided. The Molecular World series provides an integrated introduction to all branches of chemistry for both students wishing to specialise and those wishing to gain a broad understanding of chemistry and its relevance to the everyday world and to other areas of science. The books, with their Case Studies and accompanying multi-media interactive CD-ROMs, will also provide valuable resource material for teachers and lecturers. (The CD-ROMs are designed for use on a PC running Windows 95, 98, ME or 2000.)
