The reaction products of photolysis of acetic anhydride in gas phase at 25"C, where He or C 0 2 was present as buffer gas, were analyzed by gas chromatography. The extent of photodissociation was 52% 2 5% and the extent of intramolecular hydrogen transfer reaction producing acetic acid and ketene wa

โฆ Synopsis
In the flash photolysis of Hg(CH3:2 it is shown that approsimntely 85% of the CH3 radicals are produced in escited vibrational states. Hate coefficients were measured for relaxation of the free radicals by He, Xr. 02, CH4. C2H6 and SFg. and it is suggested that the rate is controlled by the out-of-plane bending mode. The combination of CH? radicals showed no pressure dependence do\n to total pressures of 3 torr.
