Notes:
The He(I) photoelectron spectra of dimethoxysulfane (1) and dimethoxydisulfane (2) have been recorded. The lowest energy ionizations in the PE spectrum of 1 can be explained by assuming C2 symmetry. They can be described as arising from linear combinations between the 3p lone-pair at sulfur and 2p lone-pairs at the oxygen atoms. A comparison between the calculated MO sequence of 2 for different conformations and the first PE bands shows a good agreement with an OSSO torsional angle near 90°. The highest occupied MOs of 2 can be described as linear combinations between the 3p MOs of the S2 unit and linear combinations between the 2p AOs of the oxygen atoms.
