Absolute rate constants for the reaction O(3P)+NO2→NO+O2 over the temperature range 230–339°K

Using the technique of flash photolysis-resonance fluorescence, absolute rate constants have been measured for the reaction O(3P)+NO2→ NO+O2. Over the temperature range 230–339°K, the rate constant was found to have the value k=9.12± 0.44 × 10−12cm3 molecule−1sec−1, independent of temperature. At stratospheric temperatures, this rate constant is about a factor of two faster than indicated from previous measurements.
