%S and I4N NMR spectra of nine sulphnr-nitrogen compounds are reported. It is demonstrated that "N NMR gives high signal-to-noise spectra with good discrimination of chemical shifts. It is concluded that both I4N and "S NMR can make a useful contribution to the study of sulphur-nitrogen chemistry and that '*N may have advantages over -N NMR in terms of speed of spectral acquisition and cost.
