Produktinformationen zu „Models for Bonding in Chemistry “
Even if modern molecular quantum mechanics offers the natural basis for very elaborate numerical calculations, models of bonding that avoid the more mathematical aspects of the subject, in the spirit of Coulson's Valence, are still of interest for stating elementary concepts of valence for atoms, molecules and their interactions.
Distinctive features of this book include:
Models of bonding in molecules that mostly require the solution of quadratic equations with real roots.
An introductory model of bonding in solids.
A model of long-range Van der Waal's interactions that avoid use of perturbation theory.
A simple pictorial model of the electrostatic interactions that determine the shape of H-bonded dimers.
Consistent use of atomic units from the very beginning for simplifying mathematical formulae.
A comprehensive list of references and both author and subject indices.
The book covers, in a readable manner with minimal use of mathematics, the essentials ofthe different bonds occurring in chemistry. Intended for undergraduate students in chemical physics, physical, theoretical and quantum chemistry, it is also relevant to masters and postgraduate students and to any scientist or student who requires a straightforward approach to bonding in molecules and solids.

Klappentext zu „Models for Bonding in Chemistry “
A readable little book assisting the student in understandin, in a nonmathematical way, the essentials of the different bonds occurring in chemistry. Starting with a short, self-contained,introduction, Chapter 1 presents the essential elements of the variation approach to either total or second-order molecular energies, the system of atomic units (au) necessary to simplify all mathematical expressions, and an introductory description of the electron distribution in molecules. Using mostly a 2x2 Hückel secular equation, Chapter 2, by far the largest part of the book because of the many implications of the chemical bond, introduces a model of bonding in homonuclear and heteronuclear diatomics, multiple and delocalized bonds in hydrocarbons, and the stereochemistry of chemical bonds in polyatomic molecules, in a word, a model of the strong first-order interactions originating the chemical bond. Chapter 3 the Hückel model of the linear polyene chain is used to explain the origin of band structure in the 1-dimensional crystal. Chapter 4 deals with a simple two-state model of weak interactions, introducing the reader to understand second-order electric properties of molecules and VdW bonding between closed shells. Lastly, in Chapter 5 studies the structure of H-bonded dimers and the nature of the hydrogen bond, which has a strength intermediate between a VdW bond and a weak chemical bond. Besides a qualitative MO approach based on HOMO-LUMO charge transfer from an electron donor to an electron acceptor molecule, a quantitative electrostatic approach is presented yielding an electrostatic model working even at its simplest pictorial level. A list of alphabetically ordered references, author and subject indices complete the book.
