The effects of sulphuric acid, perchloric acid, and nitrobenzen on the yield and decay of trapped electron, e e -, in methanol glass have been studied by pulse radiolysis at temperatures between 6 and 120 K. The effect of isotopic substitution by deuterium was examined in the case of the acid glasses. Some comparative studies were also carried out in ethanol and MTHF glasses. In all cases the presence of acid or nitrobenzene reduced the yield of e - t and enhanced its subsequent decay. Both the yield and decay of e - t in the presence of the solutes were found to depend significantly on temperature. It is considered that the reaction of e - t with hydrogen-ion and the temperature dependences of the reactions are inconsistent with processes involving long-range tunnelling by e -. Alternative mechanism for the reactions are discussed.
