The pulse radiolysis of a Freon mixture (FM), an equivolume mixture of CFCl3 and CF2BrCF2Br, at 77 K gave transient absorption bands with peaks at 360, 490, and 530 nm, whose decay was enhanced by cation scavengers: propylamine, triethylamine, N,N′-diethylaniline, and biphenyl. The degree of the enhancement was independent of the difference in the ionization potential between the matrix and the solute molecules. In the FM matrix, positive-charge transfer from biphenyl cations to some other solute molecules showed energy dependence similar to that observed in the s-butyl chloride matrix. The rate of inter-solute positive-charge transfer was faster in the FM matrix than in the s-butyl chloride matrix. These results were discussed in relation to current electron transfer theories.
