Gamma irradiation damage centres in (NH4)2SiF6, (NH4)2SnCl6, (NH4)2PtCl6, [(CH3)2NH2]2SnCl6, (NH4)2PdCl6 and ultraviolet irradiation damage centres in (CH3)4NCH3COO and (CH3)4NBr have been investigated by electron paramagnetic resonance spectroscopy. It has been found that the radicals produced in (NH4)2SiF6 and (NH4)2SnCl6 is N2H4+, and those in (NH4)2PtCl6 are NH3 and (PtCl6)3-. In [(CH3)2NH2]2SnCl6 the species is (CH3)2NH+, and in (NH4)2PdCl6 the species is (PdCl6)3-. Furthermore, it has been shown that the ultraviolet irradiation produces CH3 and CO2_radicals in (CH3)4NCH3COO and CH3 radical in (CH3)4NBr. The EPR parameters of the observed radicals have been determined. © - Verlag der Zeitschrift für Naturforschung
