The rate constant for the reaction of O(") with H202 was measured as a function of temperature and the [H202]0/[0]0 ratio. The numerical solution of the appropriate rate equations was used to arrive a t a mechanism which adequately describes our results and the rather divergent data in the literatur

The rate constant of the reaction OH (v = 0) + O3 5 HOa + 02 was measured over the temperature range from 220 to 4-50'K at total pressures between 2 and 5 torr using ultraviolet fluorescent scattering for the detection of OH radicals. An Arrhenius spression, ICI = 1.3 X lo-l2 x esp(-1900/RT) cm3/s
## Abstract Pulse radiolysis techniques were used to measure the gas phase UV absorption spectra of the title peroxy radicals over the range 215β340 nm. By scaling to Ο(CH~3~O~2~)~240 nm~ = (4.24 Β± 0.27) Γ 10^β18^, the following absorption cross sections were determined: Ο(HO~2~)~240 nm~ = 1.29 Β± 0
The rate constants for the reactions OH(X 'II, kl k2 u=O) + NH3 --t HzO+ NH? and OII(X '11, u=O) + O3 -HO, + O2 were measured at 296K by the flash photolysis resonance fluorescence technique. The values of the rate constants thus obtained are kl = (4.1 +-0.6) X lo-l4 nndkz = (6.5 t 1.0) X lo-l4 in u
