✦ Synopsis
Rates of V-T transfer for vibrationally excited ozone (Oi) in the (loo), ( 010) and ( 001) levels have been measured using a laser enhanced chemiluminescent method for the deactivating gases He, Ar, Hz, N2,02, H20, CO2, SO2, CH4, and SF6. The method takes advantage of an enhanced reaction rate between 05 + NO producing electronically excited NO2 and uses the NO2 chemiluminescence as a tracer for the 01 concentration. Results obtained by this new method are compared with recent results obtained by an IR fluorescence method. Good agreement is obtained for all gases, except methane, and implications of these results on the mechanism for deactivation are described.
