Article abstract of DOI:10.1021/j100243a030

The kinetics of the reactions O(3P_J) + H2O2 -> products (k₁) and O(3P_J) + O3 -> 2O2 (k₂) have been investigated as a function of temperature over the temperature ranges 298-386 and 237-377 K, respectively.O(3P_J) was produced in the absence of other reactive free radicals by 532-nm pulsed laser photolysis of O3 and detected by time-resolved resonance fluorescence spectroscopy.The following Arrhenius expressions adequately describe the experimental results: k₁=(1.13 +/- 0.54)*10^-12 exp<-(2000 +/- 160)/T> and k₂=(5.6 +/- 2.1)*10^-12 exp<-(1950 +/- 110)/T> (units are cm³ molecule^-1 s^-1, errors are 2?).
