ESR of [FORMULA OMITTED]NH2 and [FORMULA OMITTED]N2[FORMULA OMITTED] Free Radicals Produced by Gamma Irradiation in NH3OHCl, (NH3OH)2SO4 and N2H6SO4

Abstract

Free radicals produced by gamma irradiation in single crystals of hydroxylammonium chloride, hydroxylammonium sulfate and hydrazinium sulfate have been investigated at room temperature with ESR. The radicals in the hydroxylammonium salts were identified as [FORMULA OMITTED]NH2 and that in hydrazinium sulfate as [FORMULA OMITTED]N2 [FORMULA OMITTED]. The ESR spectra of the radicals were unchanged and undiminished at room temperature more than eight months after irradiation. The g and hyperfine constants were found to be almost isotropic with an average g = 2.0047, aH = 2.0 mT and ?N = 0.70 mT for [FORMULA OMITTED]NH2 and g = 2.0034, aH = l.lOmT and aN = 1.15 mT for [FORMULA OMITTED]N2[FORMULA OMITTED]. © 1985, Walter de Gruyter.
