The epr spectrum of a persistent sulfur nitride radical cation, common to the oxidation of many sulphur–nitrogen compounds, has been obtained from materials highly enriched in both 15N and 33S. Analyses of solution and frozen spectra show that the carrier is planar S3N2+ and that its ground state is 2A2 in C2v. symmetry.

The e.p.r. spectra of the Fe-proteins of nitrogenase from all sources studied have unusual features in that they have very anisotropic linewidths and low integrated intensities. These characteristics can be explained by assuming that one of the two electrons accepted by these proteins is located at a rapidly relaxing paramagnetic centre that is unobservable by e.p.r., but causes anisotropic broadening of the e.p.r. signal of the other electron. Complex-formation between Fe-proteins and MgATP is described in terms of a 50-60 degrees rotation of the e.p.r.-observable centre.
