The EPR spectra of 7-irradiated powders of acetyl-β-methyl choline chloride (AβMCCl) and carbamyl-β-methyl choline chloride (CβMCCl) indicated the existence of the [Me3NĊMeCH2OCOMe]Cl radical in the former and of the [Me3NĊMeCH2OCONH2]Cl radical in the latter.

Abstract 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 irradia­ tion produces ĊH3 and CO2- radicals in (CH3)4NCH3COO and ĊH3 radical in (CH3)4NBr. The EPR parameters of the observed radicals have been determined.
