Further pulse radiolysis investigations of the formation of the biphenyl radical cation enhanced by diphenyliodonium salts in dichloromethane solution are reported. The slow formation of the radical cation in the presence of Ph/sub 2/IPF/sub 6/ (or Ph/sub 2/IAsF/sub 6/) is also observed in 1,2-dichloroethane but not in acetone, acetonitrile, and ethyl acetate. It was suggested that the free radicals generated from the chlorohydrocarbon solvents are largely responsible for the slow formation of the radical cation. Results with naphthalene, anthracene, and pyrene are also presented. The contribution of the excited states of the aromatic compounds, which have been proposed to be the precursors of the radical cations by a photolysis study, is not important in the pulse radiolysis. The effects of the salts in the radiolysis are compared with those in the photolysis.
