• The Ar-, Kr-, and Xe-sensitized radiolyses of toluene was studied at room temperature in the gas phase. The discussion was concentrated on the formation of three isomers of methyldiphenylmethane (MDPM), which, it had been suggested in a previous paper on the direct radiolysis of toluene, were formed by the ion-molecule reaction of C<SUB>7</SUB>H<SUB>7</SUB><SUP>+</SUP> ions. The sensitization effect on the MDPM formation was extremely large in the case of Ar, and decreased in the order of Ar, Kr, and Xe. These results were explained in terms of charge transfer from these rare gases to toluene, resulting in the formation of the C<SUB>7</SUB>H<SUB>7</SUB><SUP>+</SUP> ions. The isomer distribution of MDPM's in the raregas-sensitized radiolysis was considered on the basis of the reaction mechanism proposed previously. The sensitization effect on the formation of other products was also discussed briefly.
