[en] The formation of dihalide ions in the pulse radiolysis of concentrated lithium bromode and chloride solutions in methanol has been studied. It has been shown that the bromide ions are oxidized by the precursors of the methoxy radicals, most probably by CH₃OH⁺ ions (''vacancies''). The difference between the capturing efficiency of the ''vacancies'' by the bromide and chloride ions can be attributed to the difference between the ionization potentials of the halide ions in liquid methanol. It has been demonstrated that the increase in the yield of free solvated electrons in the radiolysis of solutions of acceptors-reducing agents cannot serve as a measure for the reactivity of the latter with respect to the ''vacancies.''
