✦ 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
