The photolysis and radiolysis of equimolar CH/sub 4/-CD/sub 4/ mixtures were investigated as a function of pressure. The fact that, in the presence of NO, the ethane fraction consists entirely of C/sub 2/D/sub 6/, C/sub 2/D/sub 4/H/ sub 2/, C/sub 2/H/sub 4/D/ sub 2/, and C/sub 2/H/sub 6/ in comparable amounts indicates that CH/sub 2/ and CD/sub 2/ are produced. The relative yield of the ethanes that are formed by insertion of methylene into methane increases with pressure in both the photolysis and radiolysis. In the radiolysis, the G value reaches a value of 0.35 plus or minus 0.1 at pressures above 15 atm. Information about the effect of pressure on the production of the ethyl ion was obtained by investigating the radiolysis of CH/sub 4/-C/sub 4/D/sub 10/ and CD/ sub 4/--C/sub 3/H/sub 8/ mixtur es from 1.5 cm to 130 atm. The data indicate that there is a gradual decrease of the ethyl ion yield with increase in pressure while the parert ion yield increases with increase in pressure to a pressure of at least 15 atm.
