## Abstract ^13^C n.m.r. spectra of methyl substituted thianes and thianium cations have been determined. The magnitude of the ^13^C substituent effects of an equatorial methyl group or of a __gem__‐dimethyl grouping appear to depend in a systematic way on whether the carbon atom concerned is adjac
The chemical shifts and line-shapes of cross-polarisation-magic-angle sample spinning . 13C-n m-r. resonances have been analysed for p-nitrophcnol, p-hydroxybenzoic acid, benzoic acid, and m-nitrophenol in the solid state and likewise for inclusion complexes with host cyclomalto-hexaose and -heptaos
