Symmetry-related atomic orbital integrals

Throughout the book, theoretical concepts and experimental evidence are integrated An introductory chapter summarizes the principles on which the Periodic Table is established and describes the periodicity of various atomic properties which are relevant to chemical bonding. Symmetry and group theory are introduced to serve as the basis of all molecular orbital treatments of molecules. This basis is then applied to a variety of covalent molecules with discussions of bond lengths and angles and hence molecular shapes. Extensive comparisons of valence bond theory and VSEPR theory with molecular orbital theory are included Metallic bonding is related to electrical conduction and semi-conduction. 

The molecular orbitals are assumed to be linear combinations of atomic symmetry basis orbitals and the coefficients in the linear relations, together with the corresponding orbital energies, are derived from a set of secular determinants, one for each symmetry species, having the form I Fqs — EiGqs I = 0. Here the group overlap integral Gqs, defined by...
