Notes:
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 \documentclass{article}\pagestyle{empty}\begin{document}$$ k_1^{{\rm air}} = (1.07 \times 10^{ - 34})\exp (525/T){\rm cm}^{\rm 6} /{\rm molecule}^{\rm 2} {\rm sec} $$\end{document} or \documentclass{article}\pagestyle{empty}\begin{document}$$ k_1^{{\rm air}} = (6.3 \times 10^{ - 34})\exp (T/300)^{\rm - 1.9}{\rm cm}^{\rm 6} /{\rm molecule}^{\rm 2} {\rm sec} $$\end{document} Comparisons of these results with existing literature data are presented.
