Temperature Dependence of the Self-Reaction of CH3O2 Radicals

Article abstract of DOI:10.1021/j150620a023

The flash photolysis-ultraviolet absorption technique was used to measure the rate constants for the reaction CH3O2 + CH3O2 -> products (1) over the temperature range 248-417 K and the pressure range 60-700 torr of N2.Rate constants were measured by observing the second-order disappearance of CH3O2 radicals.The measured Arrhenius expression is k₁ = (1.40 +/- 0.20) x 1E-13 exp<(223 +/- 41)/T>cm³ molecule^-1 s^-1, where the rate constant is defined by the expression -d/dt = 2k₁².
