The order of the combination reaction CH3 4 O2 has been shown to lie bet;Keen two and three throughout the pressure range from 30 to 380 torr at 22 rE ZยฐC, and the limiting value of the second order rate constant at high pressure is (2.7i0.2) X 108 Like moIe'I se& \_
Methylperoxy radicals were generated by the flash photolysis of azomethane-oxygen mixtures. The observed broadband spectrum of the CH302 radical is similar, but not identical to those reported previously. The CH:302 decay followed second-order kinetics a t high CH:jOz concentrations with k4, = (2.5
