15 N, 17 O and 33 S NMR chemical shifts were determined for some aliphatic and aromatic sulphonamides, sulphinamides, sulphenamides and related sulphones and sulphoxides. The 17 O and 33 S NMR chemical shifts change only slightly for the sulphonyl compounds. In the sulphinyl compounds, on the other hand, the presence of nitrogen causes a noticeable shift to higher frequencies in the 17 O resonance. The differences between the 17 O chemical shifts of sulphinyl and sulphonyl compounds are more noticeable than those between sulphinamides and sulphoxides. The 15 N NMR chemical shifts of sulphon‐, sulphin‐ and sulphen‐amides reflect well the effect of the environments of both nitrogen and the adjacent sulphur atom. The correlations between 15 N, 17 O and 33 S NMR chemical shifts and the structures of sulphur amides and related sulphones and sulphoxides are discussed. The chemical shifts of the 13 C nuclei are also presented.
