A reinvestigation of the temperature dependence of the rate constant for the reaction O + O2 + M → O3 + M (for M = O2, N2, and Ar) by the flash photolysis resonance fluorescence technique

The flash photolysis resonance fluorescence technique has been used to reinvestigate the kinetics of the oxygen atom–oxygen molecule combination reaction. Third-order rate constants for O₂, N₂, and Ar as deactivant molecules were determined over the temperature range of 219–368 K. The results presented herein are the most extensive data sets available for atmospheric modeling and are used to formulate a recommendation for such purposes. The recommended rate expressions are or Comparisons of these results with existing literature data are presented.
