✦ Synopsis

15N, 1 7 0 and 33S N M R chemical shifts were determined for some aliphatic and aromatic sulphonamides, sulphinamides, sulphenamides and related sulphones and sulphoxides. The 1 7 0 and NMR chemical shifts change only slightly for the sulphonyl compounds. In the sulphinyl componnds, on the other hand, the presence of nitrogen causes a noticeable shift to higher frequencies in the 1 7 0 resonance. The Merences between the 1 7 0 chemical shifts of sulphinyl and snlphonyl compounds are more noticeable than those between sulphinamides and sulphoxides. The 15N NMR chemical shifts of sulphon-, sulphin-and sulphenamides reflect well the effect of the environments of both nitrogen and the adjacent sulphur atom. The correlations between "N, 170 and 33S NMR chemical shifts and the structores of sulphur amides and related sulphones and sulphoxides are discussed. The chemical shifts of the -C nuclei are also presented.
