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.

Inorganic Chemistry This series reflects the breadth of modernresearch in inorganic chemistry and fulfils the need for advancedtexts. The series covers the whole range of inorganic and physicalchemistry, solid state chemistry, coordination chemistry, maingroup chemistry and bioinorganic chemistry. Chemical Bonds A DialogJeremy K. Burdett The University of Chicago, USA Understanding thenature of the chemical bond is the key to understanding allchemistry, be it inorganic, physical, organic or biochemistry. Inthe form of a question and answer tutorial the fundamental conceptsof chemical bonding are explored. These range from the nature ofthe chemical bond, via the regular hexagonal structure of benzeneand the meaning of the term 'metallic bond', to d-orbitalinvolvement in hypervalent compounds and the structure of N_2O.Chemical Bonds: A Dialog provides * a novel format in terms of a dialog between two scientists * insights into many key questions concerning chemical bonds * an orbital approach to quantum chemistry

Graphene’s nickname ‘miracle material’ normally means the material superior properties. However, all these characteristics are only the outward manifestation of the wonderful nature of graphene. The real miracle of graphene is that the specie is a union of two entities: a physical - and a chemical one, each of which is unique in its own way. The book concerns a very close interrelationship between graphene physics and chemistry as expressed via typical spin effects of a chemical physics origin. Based on quantum-chemical computations, the book is nevertheless addressed to the reflection of physical reality and it is aimed at an understanding of what constitutes graphene as an object of material science – sci graphene – on the one hand, and as a working material- high tech graphene - for a variety of attractive applications largely discussed and debated in the press, on the other. The book is written by a user of quantum chemistry, sufficiently experienced in material science, and the chemical physics of graphene is presented as the user view based on results of extended computational experiments in tight connection with their relevance to physical and chemical realities. The experiments have been carried out at the same theoretical platform, which allows considering different sides of the graphene life at the same level in light of its chemical peculiarity.

Chemical Bonds and Bonds Energy, Second Edition provides information pertinent to the fundamental aspects of contributing bond energy and bond dissociation energy. This book explores the values that are useful in the interpretation of significant phenomena such as product distribution and reaction mechanisms. Organized into 12 chapters, this edition begins with an overview of the quantitative relationship among three basic properties of an atom, namely, nonpolar covalent radius, electronegativity, and homonuclear single covalent bond energy. This text then examines the quantitative means of evaluating the partial atomic charges that result from initial differences in the electromagnetivity of atoms that form a compound. Other chapters consider the recognition of the reduction of bond weakening not by multiplicity and in certain types of single covalent bonds. The final chapter deals with the application of the principal ideas and techniques to the oxidation of ethane. This book is a valuable resource for organic and inorganic chemists.

Providing the quantum-mechanical foundations of chemical bonding, this unique textbook emphasizes key concepts such as superposition, degeneracy of states and the role of the electron spin. An initial, concise and compact presentation of the rudiments of quantum mechanics enables readers to progress through the book with a firm grounding. Experimental examples are included to illustrate how the abstract concepts are manifest in real systems.

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
