The C-18 and C-19 methyl resonances of 5a-androstane occur at s = 0.69 p.p.m. and 6~0.79 p.p.m. in deuteriochloroform solution (I) and at dzO.71 p.p.m. and 6=0.79 p.p.m. in benzene solution .\* It therefore appears likely that in the absence of polar functional groups, no preferred geometrical relat

## Abstract A series of model sulfides was oxidized in the NMR sample tube to sulfoxides and sulfones by the stepwise addition of __meta__‐chloroperbenzoic acid in deuterochloroform. Various methods of quantum chemical calculations have been tested to reproduce the observed ^1^H and ^13^C chemical
