Abstract
IT has been suggested in the radiation chemistry of the simple aliphatic alcohols, ethanol1 and methanol2,3, that γ-irradiation in the liquid state leads to the formation of positive and negative charged species: 2CH3CH2OH→(CH3CH2OH)+ + (CH3CH2OH)− The negative species, the solvated electrons, were shown to be involved in the chemical changes observed from their reactions with certain specific solutes: H+, chloroacetate, 2-chloroethanol, diphenyl, naphthalene. More recently, various organic glasses4 were irradiated at 77° K and in the case of ethanol4,5 the absorption band formed at 5400 Å was accounted as due to solvated electrons. We present electron spin resonance evidence of radiation-induced electrons trapped or solvated in glasses at 77° K in the radiolysis of alcohols.
