Abstract
Approximate MO LCAO SCF calculations have been performed on the ions SO42−, S2O32−, SO32−, ClO4, ClO3, and ClO2. The results are applied to a discussion of chemical effects in x‐ray spectra and inner‐shell photoelectron spectra. Good agreement is obtained with charge distributions estimated from shifts of the Kα12 emission line of sulfur and chlorine. The valence‐electron molecular‐orbital structure differs considerably from that obtained from Wolfsberg—Helmholz calculations and agrees with ESR measurements on SO4 and S2O3.
