A flash photolysis resonance fluorescence investigation of the reaction OH + H 2 O 2 → HO 2 + H 2 O

The flash photolysis resonance fluorescence technique has been used to measure the rate constant for the reactionover the temperature range of 250–370 K. The present results are in excellent agreement with three very recent studies, and the combined data set can been used to derive the expressionsimilar to that currently used in atmospheric modeling applications. A summary of our computer simulation of this reaction system is presented. The results of the computations indicate the absence of secondary reaction complications in the present work while revealing significant problems in the earlier (pre‐1980) studies of the title reaction.
