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 NH2 and that in hydrazinium sulfate as N2H4+ . 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 αN = 0.70 mT for NH2 and g = 2.0034, aH = 1.10 mT and aN = 1.15 mT for N2N4+ .
