By Yukio Yamaguchi, John D. Goddard, Yoshihiro Osamura, Henry Schaefer

In sleek theoretical chemistry, the significance of the analytic review of power derivatives from trustworthy wave features can rarely be overvalued. This monograph provides the formula and implementation of analytical power by-product tools in ab initio quantum chemistry. It incorporates a systematic presentation of the mandatory algebraic formulae for the entire derivations. The assurance is proscribed to by-product equipment for wave capabilities according to the variational precept, particularly limited Hartree-Fock (RHF), configuration interplay (CI) and multi-configuration self-consistent-field (MCSCF) wave capabilities. The monograph is meant to facilitate the paintings of quantum chemists, and should function an invaluable source for graduate-level scholars of the sphere.
