The structure of radicals produced by the radiolysis of glassy cyclohexanol

The stabilization of electrons and radicals resulted from hydrogen atom loss in the 2-, 3- and 4-positions of cyclohexane ring and 1-hydroxycyclohexyl radicals in γ-irradiated glassy cyclohexanol was shown with the ESR technique. The stabilization of electrons and alkyl-type radicals was observed for the first time. The total yield of radicals and electrons is equal to 3.7+-0.5 unit per 100 eV of absorbed energy. Upon heating the irradiated cyclohexanol, the alkyltype radicals interact with the alcohol producing 1-hydroxycyclohexyl radicals (within the -155 deg C -115 deg C temperature range). Using the spin trap C-phenyl-N-tert-butylnitrone, it was shown that this reaction is not accompanied with the diffusion of radicals into the matrix but occurs due to the cage abstraction of hydrogen atom from an alcohol molecule.
