The reaction between CH3 radicals and O2 was investigated in incident shock waves at temperatures between 1390 and 2250 K and densities from 1.5 to 5.3 mol/m+30/3 using azomethane as a source of methyl radicals by following the consumption of CH3 radicals with time resolved UV absorption measurements at 213.9 nm. The rate constant expression k2=1.35 × 1012 exp( - 5900 K/T) cm3 mol-1s-1 for the reaction of CH3 + O2 → CH2O + OH was derived.
