Photoelectron spectra and molecular properties : XXI. Dimethyl sulfide, methyl silyl sulfide, and disilyl sulfide

Abstract

The photoelectron spectra of methyl and silyl sulfides are assigned on the basis of modified CNDO-SCF-MO calculations. The orbital sequence (2 b 1, 4 a 1, 3 b 2) is found to be independent of conformation. The static geometry of the sulfides is in keeping with a smaller charge shift to sulfur accompanying the carbon-silicon exchange. Comparison of the results wit those of the analogous ethers lends support to the previous assignment of the latter.
