The effects of CCl<SUB>4</SUB> on the formation of H<SUB>2</SUB> and C<SUB>4</SUB>H<SUB>9</SUB> radicals in the radiolysis of <I>i</I>-C<SUB>4</SUB>H<SUB>10</SUB> have been studied in glass at 77°K and the liquid at 195°K. The yield of H<SUB>2</SUB>, which is not affected by the addition of N<SUB>2</SUB>O or SF<SUB>6</SUB>, decreases sharply upon the addition of CCl<SUB>4</SUB> in the glass, as in the crystal (This Bulletin, <B>42</B>, 1164 (1969); <B>43</B>, 1017 (1970).), while it does not so sharply decrease in the liquid as in the solid. The effects of CCl<SUB>4</SUB> on the yields of H<SUB>2</SUB> correspond fairly well to those on the yields of the C<SUB>4</SUB>H<SUB>9</SUB> radicals. The effects of CCl<SUB>4</SUB> in the glass are explained by the excitation transfer from the excited butane molecule to CCl<SUB>4</SUB>, as in the radiolysis of <I>i</I>-C<SUB>4</SUB>H<SUB>10</SUB> in the crystal. A kinetic treatment suggests that its mechanism may be the exciton transfer. Some remarks on the primary process of ionization in the radiolysis of solid hydrocarbons are given from the viewpoint of exciton transfer.
