β¦ Synopsis
A modified scheme of a previously developed concept of atomic valence numbers in molecules is presented. The relation to population analysis is demonstrated. The scheme is suitable for ab initio wave functions with extended basis sets. The procedure involved a combination of symmetric orthogonalization and contraction of the basis set. The method is used for a systematic investigation of a series of compounds with first-row atoms from Li to F. The predicted atomic charges and valence numbers are in line with results from infrared spectroscopy and multipole moment analysis.

The ab initio effective valence shell Hamiltonian (H') method has been extended to calculate molecular properties of valence states as well as energies. Both the effective Hamiltonian and effective molecular property operator are perturbatively expanded in powers of correlation, and contain contribu
## Abstract An __ab initio__ nonorthogonal valence bond program, called XMVB, is described in this article. The XMVB package uses HeitlerβLondonβSlaterβPauling (HLSP) functions as state functions, and calculations can be performed with either all independent state functions for a molecule or prefer
