³³S and ¹⁴N nuclear magnetic resonance spectra of some sulphur–nitrogen compounds

³³S and ¹⁴N NMR spectra of nine sulphur‐nitrogen compounds are reported. It is demonstrated that ¹⁴N NMR gives high signal‐to‐noise spectra with good discrimination of chemical shifts. It is concluded that both ¹⁴N and ³³S NMR can make a useful contribution to the study of sulphur‐nitrogen chemistry and that ¹⁴N may have advantages over ¹⁵N NMR in terms of speed of spectral acquisition and cost.
