Collisional electronic quenching rates for NO A2Σ+ (ν = 0)

We report rate coefficients for electronic quenching of NO A2Σ+ (ν = 0) by CO, CO2, H2, H2O, O2, NO, N2O, NO2, and Ar measured at room temperature and at elevated temperatures behind reproducible shocks. The magnitudes of the rates and the observed temperature dependencies of NO A2Σ+ quenching by these collision partners are found to be in accord with a charge-transfer (harpoon) collision model for the process.
