This is the perfect complement to "Chemical Bonding - Across the Periodic Table" by the same editors, who are two of the top scientists working on this topic, each with extensive experience and important connections within the community. The resulting book is a unique overview of the different approaches used for describing a chemical bond, including molecular-orbital based, valence-bond based, ELF, AIM and density-functional based methods. It takes into account the many developments that have taken place in the field over the past few decades due to the rapid advances in quantum chemical models and faster computers.

Valence Shell Electron Pair Repulsion (VSEPR) theory is a simple technique for predicting the geometry of atomic centers in small molecules and molecular ions. This authoritative reference was written by Istvan Hartiggai and the developer of VSEPR theory, Ronald J. Gillespie. In addition to its value as a text for courses in molecular geometry and chemistry, it constitutes a classic reference for professionals. Starting with coverage of the broader aspects of VSEPR, this volume narrows its focus to a succinct survey of the methods of structural determination. Additional topics include the applications of the VSEPR model and its theoretical basis. Helpful data on molecular geometries, bond lengths, and bond angles appear in tables and other graphics.

Molecular surface science has made enormous progress in the past 30 years. The development can be characterized by a revolution in fundamental knowledge obtained from simple model systems and by an explosion in the number of experimental techniques. The last 10 years has seen an equally rapid development of quantum mechanical modeling of surface processes using Density Functional Theory (DFT). Chemical Bonding at Surfaces and Interfaces focuses on phenomena and concepts rather than on experimental or theoretical techniques. The aim is to provide the common basis for describing the interaction of atoms and molecules with surfaces and this to be used very broadly in science and technology. The book begins with an overview of structural information on surface adsorbates and discusses the structure of a number of important chemisorption systems. Chapter 2 describes in detail the chemical bond between atoms or molecules and a metal surface in the observed surface structures. A detailed description of experimental information on the dynamics of bond-formation and bond-breaking at surfaces make up Chapter 3. Followed by an in-depth analysis of aspects of heterogeneous catalysis based on the d-band model. In Chapter 5 adsorption and chemistry on the enormously important Si and Ge semiconductor surfaces are covered. In the remaining two Chapters the book moves on from solid-gas interfaces and looks at solid-liquid interface processes. In the final chapter an overview is given of the environmentally important chemical processes occurring on mineral and oxide surfaces in contact with water and electrolytes. Gives examples of how modern theoretical DFT techniques can be used to design heterogeneous catalysts This book suits the rapid introduction of methods and concepts from surface science into a broad range of scientific disciplines where the interaction between a solid and the surrounding gas or liquid phase is an essential component Shows how insight into chemical bonding at surfaces can be applied to a range of scientific problems in heterogeneous catalysis, electrochemistry, environmental science and semiconductor processing Provides both the fundamental perspective and an overview of chemical bonding in terms of structure, electronic structure and dynamics of bond rearrangements at surfaces

MOLECULES AND THE CHEMICAL BOND & Other Leading Chemical Concepts Simplified This highly original book by a noted chemist and chemical educator may change the way newcomers to chemical thought learn and the way its connoisseurs think about - * Atomic Theory * The Mole Concept and Avogadro's Constant * The Gas Laws * Solving Problems in Chemical Stoichiometry * The Saturation and Directional Character of Chemical Affinity * The Pauli Exclusion Principle * Linnett's Double Spin Set Theory * Pauling's Rules of Crystal Chemistry * The Octet Rule * Lewis Structures for O2, NO, CO, SO2 and SO3 * Construction of Bond Diagrams * VSEPR Theory * Dative Bonding * Multicenter Bonding * Bonding in Metals * pH Calculations * The Periodic Table * The Energy Function and the First Law of Thermodynamics * The Entropy Function and the Second Law of Thermodynamics * How an Inductive Science Advances Dedicated to students, teachers, and professionals in the pure and applied sciences who might welcome an account of molecular structure that, in Einstein's words is as simple as possible but [it's believed] no simpler and that provides, thereby, in Gibbs' words, a point of view from which the subject appears in its greatest simplicity, MCB is several books interlaced. It is a novel account of evidence for atoms; an historical account of the development classical structural theory of molecules; a simple, step-by-step guide on how to draw scientifically sound bond diagrams; an exclusive orbital model of bonding that embraces from one point of view covalent, ionic, and metallic bonding; philosophical justifications for uses of molecular models; explanations for a number of previously unexplained molecular features; domestication for easy use in valence theory of fundamental principles of quantum physics; and, withal, a short textbook of general chemistry in a new key. Principally MCB is a highly visual account of a chemical mechanics of the Pauli Exclusion Principle, in the form of the story of a stroke, a stick, and a sphere and what happens if one takes chemists' seemingly unsophisticated cartoons of molecules and their corresponding tinker-toy-like ball-and-stick models seriously. One theme runs through the book: the nature of the inductive sciences, illustrated by the union of facts and ideas with creation of concepts and models, principles and rules that, jointly, comprise what is called in MCB "Conceptual Valence Bond Theory". The book has been described "as a pedagogical hierarchy of progressively more sophisticated treatments of an easily visualizable model of the chemical bond." In the words of the author's daughter (a chemist) - "This book is the culmination of my Father's insights into the molecules he has literally breathed, consumed, and digested, for the past 84 years. It is his intimate knowledge about the elements, learned from a lifetime of reading, experimenting, and teaching that makes this book different. Dad truly loves (and believes in!) molecules, and that single tenet comes across on every page. Flat valence stroke diagrams are inflated to three dimensional valence sphere models whose geometries correlate with calculations and provide, with ease, explanations for reaction mechanisms, multicenter bonds, and molecular geometries considered exceptions or unexpected . Describing molecules as hypervalent or electron deficient suggests something abnormal or unnatural, and is misleading since nature is always natural . Concepts such as the gas laws and the energy function are presented from an historical perspective, and with algebraic rigor, eliminating inconsistencies that bug you as a chemistry student, but you can't really put your finger on why. From the correct placement of helium above beryllium in the periodic table, to pointing out the problems with omitting nucleus-electron attractions in the popular Valence Shell Electron Pair Repulsion theory (where correct conclusions regarding molecular shapes support an incorrect conce
