Hydrogen Abstraction from Hydrocarbons by Methyl Radicals from the Photolysis of Methyl Iodide in Solid Nitrogen
Methyl iodide was photolyzed at 20 deg K, in solid matrix materials, N/ sub 2/, Kr, and Xe, containing hydrocarbons STAC/sub 2/H/sub 6/ or (CH/sub 3/)/ sub 3/CH! or deuterated hydrocarbons STACD/sub 4/, CH/sub 3/CD/sub 3/, or (CH/sub 3/)/sub 3/CD!. Hydrogen abstraction was studied by infrared detection of CH/sub 4/ and CH/sub 3/D. In the solid the abstraction products can be attributed to methyl radicals with an effective temperature in the range 1000-3000 deg K. Furthermore, the products obtained from photolysis of methyl iodide with ethane present as well as those from photolysis of ethyl iodide in nitrogen, indicate that about 85% of the reactions probably occur within the cage at the site of photon absorption. These studies provide information concerning the dissipation of the energy of a hot radical constrained within a reactive cage. (auth)
