An electron spin resonance study of the free radicals induced in O-methylisouronium chloride by X-irradiation at 77°K
Abstract
Electron spin resonance studies of single crystals of O-methylisouronium chloride show that two types of radicals are produced by irradiation at 77°K with X-rays. On annealing at room temperature, these decay to yield one room temperature-stable species. The structures of both low temperature- and room temperature-stable radicals are discussed.
