Radiolysis of Simple Aromatics in Boric Acid Glass

Abstract
Electron paramagnetic resonance studies have been made of the stable free radicals produced by x irradiation of aromatic hydrocarbons dissolved in partially dehydrated boric acid glass. In general, singly charged molecular ions were not found to be the sole species. Deuterium substitution in the boric acid glass showed that all end point radicals contained hydrogen from the matrix. All glasses exhibited a 100–140 G EPR pattern, which has been interpreted as that of radicals produced by formation of a —CH2— group in a benzene ring.
