The vertical ~oniznt~on potentials of the HF molecule were calculated by Raylegh-Schrodmger perturbation theory wth M cktenswe basis set of contracted gnu&n-type orbitis. The results are compared with cxistmg eupetunenlal values as WCU as those calculated by more elaborate many-body tecluuqucs.
The relatively economical procedure of the combined USC of effective core potentials and perturbation corrections to Koopmans' theorem has been applied to chloroketene and dichloroketene. A clearcut assignment of all the bands in the He1 photoelectron spectra is established.
