Abstract The stabilization of electrons and radicals resulted from hydrogen atom loss in the 2-, 3- and 4-positions of the 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 units per 100 eV of absorbed energy. Upon heating the irradiated cyclohexanol, the alkyl-type radicals interact with the alcohol producing 1-hydroxycyclohexyl radicals /within the −155 °C÷115 °C temperature range/. Using the spin trap C-phenyl-N-tert-butylnitrone, it has been shown that this reaction is not acompanied by the diffusion of radicals into the matrix but occurs due to the cage abstraction of hydrogen atom from an alcohol molecule.
