A laser flash photolysis-resonance fluorescence technique has been employed to study the kinetics of the important stratospheric reactions Cl('P,) + O 3 C10 + O2 and Br('P,,,) + O3 -+ BrO + O2 as a function of temperature, The temperature dependence observed for the Cl('P,) + O3 reaction is nonArrhe
