Abstract
The effect of substituents on the spectral behavior of some arylthiome thyl benzoic acid derivatives, the corresponding sulfoxides and sulfon es were studied. The chemical shifts of ortho hydrogen of benzyl moiet ies gave linear correlations with Hammett constants for acid sulfides and concave curves for sulfide esters. The effect of substituents on t he conformation of sulfides were discussed.
