Nitrogen-14 nuclear magnetic resonance studies on sulphur–nitrogen compounds

Abstract
The 14N n.m.r. spectra of a variety of sulphur–nitrogen heterocycles and metal–sulphur–nitrogen complexes have been recorded and the observed shifts correlated with bonding type. The utility of 14N n.m.r. spectroscopy as a mechanistic tool in sulphur–nitrogen chemistry is illustrated for reactions in liquid ammonia.
