β¦ Synopsis
The absolute rate constant of the title reaction has been measured using the technique of discharge flow resonance fiuorcscencc over the temperature range X3-373 K. An Arrhcnius plot of the data below room temperature can be fittedbp a nc_Wive activation energy E/R = -S43 K. The room-temperature value of the rate constant kt = (0.93 f 0.10) x lo-l3 cm3 molecule-' s-' . . 1s m excellent agreement with previous discharge flow studies using optical dctcction but lies significantly below the results from flash photolysis investigations.

## Abstract The flash photolysis resonance fluorescence technique has been used to reinvestigate the kinetics of the oxygen atomβoxygen molecule combination reaction. Thirdβorder rate constants for O~2~, N~2~, and Ar as deactivant molecules were determined over the temperature range of 219β368 K. T
