Proton Magnetic Resonance Spectra of Some Organosulfur Compounds

The proton magnetic resonance spectra of various sulfur derivatives of long-chain carboxylic acids have been studied The types of compounds studied include those where the methylene chain is interrupted by a sulfide or a sulfone group and those where the carboxyl group has been replaced by –SO3– or –C(=O)S–. The spectral effects produced by the sulfur-containing groups are discussed. The effect of the sulfur group in sulfides and sulfones is compared with the effect of an oxygen atom in a similar environment. The effect of the –SO3– and –C(=O)S– groups on neighboring methylene groups is compared with the effect of the carboxyl group.
