✦ Synopsis

Mixtures of Cl:!, CH4, and 0 2 were flash photolyzed a t room temperature and pressures of -60-760 Torr to produce CH3O2. The CH3O2 radicals decay by the second-order process (6) 2CH302products with k g = (3.7 f 0.3) X cm3/sec in good agreement with other studies. This value ignores any removal by secondary radicals produced as a result of reaction ( ), and therefore the true value might be as much as 30% lower. The value is independent of total pressure or the presence of HzO vapor. With SO2 also present, the CH3O2 decay becomes pseudo first order a t sufficiently high SO:! pressure which indicates the reaction

The value of (8.2 f 0.5) X cm3/sec a t about 1 atm total pressure (mostly CH4) was found for CH302 removal by Son, in good agreement with another recent measurement. This value can be equated with k l , unless the products rapidly remove another CH302 radical, in which case k 1 would be a factor of 2 smaller.
