Spin Resonance Study

γ-Irradiation of polycrystalline tetraethylammonium iodide at 77°K leads to the breaking of a C—C bond and the primary radicals ĊH3 and [Formula: see text] were detected by electron spin resonance. The methyl radicals were found to disappear readily at 120°K. In the range of 263–273°K a secondary reaction between [Formula: see text] and the parent ion [Formula: see text] was observed; the resulting secondary radical [Formula: see text] was found to be stable up to 373°K.
