Theoretical and experimental inner shell ionization potentials (IP) have been determined for (CH3)2S and (CH3) 2SO. This information is combined with other data to draw conclusions on the effect of methyl and phenyl substituents in the series R2S, R2SO and R2SO2, on the chemical shifts of the sulphur 2P IP. It was found that while methyl substitution has no significant effect on the chemical shifts of the sulphur 2P IP, phenyl substition modifies them significantly implying a donation of electron density from the phenyl groups to sulphur.
