The electron spin resonance spectrum of NH(SO₃^-) in γ-irradiated potassium sulphamate

Abstract

The electron spin resonance spectrum of the radical NH(SO3 - trapped in a single crystal of potassium sulphamate is interpreted. The hyperfine couplings for the hydrogen and nitrogen nuclei are given. The radical is planar, the unpaired electron occupying an orbital of π symmetry being predominantly a nitrogen 2p orbital.
