NH A 3Πi quenching at 1400 K

摘要: We have measured electronic quenching rate constants, kQ, in the NH A 3Πi, v’=0 state for several quencher molecules at 1400 K. The radicals were produced a laser pyrolysis apparatus when mixture of SF6, CF4, NH3, and added was irradiated by CO2 laser. ground then excited to A pulsed tunable dye fluorescence decay rates as function pressure yielded constants. thermally averaged cross sections, σQ=kQ/〈v〉, K are all smaller than those observed OH 1200 this laboratory. In most cases, our high temperature σQ’s same elsewhere room temperature. These experimental less calculated with an attractive forces ‘‘collision complex’’ model.
