✦ Synopsis


Photoelectron spectra of benzene, pyridinc, cthylcnc, aone and butiidiene are cAculated by USC of tbc MO SCF method HAM/3. Since the correlation energy errors ~cem to be negligible in this method, Koopmane' theorem cannot be used. Instead, a transitIon state procedure is used. The calculations are compared wrth expcrimcntnl photoclcctron spectra

## Abstract Further developments of a recent semiempirical, variable effective charge MO theory for calculation of ionization potentials (IP) and electron affinities (EA) as energy differences between separately minimized ground and ionized states are reported. The method is extended to adiabatic a
