The 170, 15N and =C NMR chemical shifts have been determined for N,N-dimethylmethanesulphinamide (l), both as the neat liquid and in dimethyl sulphoxide, acetone, chloroform and various alcohols. The 0 and 15N nuclei of 1 resonate at a lower frequency than those of the corresponding sulphonamide, an
