The flash photolysis-resonance fluorescence technique has been utilized to measure the rate constants for the reactions of chlorine nitrate (ClONO2) with two stratospheric radicals, O(3P) and OH. Both rate constants were measured at a pressure of 20 Torr and a temperature of 245 K. The reactions with their corresponding rate constant in units of cm-3 molecule-1s-1 are: O(3P)+ClONO2→Products, k1= (2.0¿0.2) ¿10-13; OH+ClONO2→Products, k2= (3.7¿0.2) ¿10-13. The above results, coupled with the photolysis rate of ClONO2, indicate that these chemical degradation pathways contribute less than 10% to the removal of ClONO2 in the stratosphere. |
