Abstract:

Recent work in our laboratory has concentrated on the kinetics of metastable molecular nitrogen, N2A 3 sigma sub u. Investigations have included measuring v-level specific bimolecular rate constants for the reactions of N2A, or 6 with relatively efficient electronic quenchers 02, NO, CO, N2O, and C2H4 and inefficient electronic quenchers CH4 and CF4. The latter set of quenchers has provided information on the relative N2A, v population distribution in the discharge flow reactor for various N2A 3 sigma sub u generating reactions and N2 concentrations. In addition, v-level specific rate constants are measured for the reaction N2A v or 3 O3P and measured the absolute nitric oxide product yield in the reaction N2A O2O3P as a function of the relative N2A, v population distribution using calibrated NO LEF.
