Kinetics results from the UV absorption experiments. a) CH₂OO time traces for [CH₃COOH] in the range (1.86–22.39)×10¹² cm⁻³, and fits to the experimental data. b) Dependence of the decay constant of CH₂OO on [CH₃COOH]. The solid line is a fit to the experimental data with the slope as the second-order rate coefficient for the CH₂OO+CH₃COOH reaction. Error bars shown are 15 % of the nominal value as estimated from repeated experiments at identical conditions.
