A readable little book assisting the student in understanding, 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
2x2 Huckel secular equations, 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. In Chapter 3 the Huckel 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, 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.
