Abstract
Total removal rate constants from the NH(A3IIi) electronic state have been obtained in low pressure (~14-Torr) N2O flames. The fluorescence decay constants and quantum yields Φ depend on the temperature and composition at each position interrogated in the flame. In similar conditions, Φ for NH(A3IIu) is significantly greater than that for other radicals CH(A2Δ and B2Σ-) and OH(A2Σ+). A small decrease (~5%) in the electronic removal is observed with rotational excitation increasing from N′ = 2 to 12 in the A state. Estimates of collisional quenching cross sections at flame temperatures are made for the important combustion species, H2O, C3H8, C2H4, and C2H2.
