✦ Synopsis

DF-CL studies using NO2 chemiluminescence detection of 0 yielded a rate constant kl for 0 + SiH4 of (2.6 5 0.5) xlO-I3 cm3 s-' at 295 K, where the 95% confidence interval reflects accuracy. FP-RF studies using flash photolysis of SO2 followed by time-resolved vuv fluorescence detection of 0 at 295 K yielded kl = (3.0 5 0.5) X cm3 s-I. These results are in good accord with most previous measurements and lead to a combined best estimate of kl = (3.2 2 0.4) X cm3 s -l . The DF-CL and FP-RF methods appear to have little unrecognized systematic error.

## Abstract 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 O~2~, N~2~, and Ar as deactivant molecules were determined over the temperature range of 219–368 K. T
