报道了皮秒激光光谱在火焰中时间分辨激光诱导荧光的碰撞猝灭率测量中的首次应用。碰撞猝灭率对激光诱导荧光法测定物质浓度有重要意义。R(2)(4) A(2) σ (+) （nu' = 0）激发后的碰撞淬火寿命？在常压预混甲烷-空气火焰的燃烧气体区，X(2)II （nu' = 0）跃迁值为1.8 nsec。
Data are reported for the first known application of picosecond laser spectroscopy to the measurement of collisional quenching rates by time-resolved laser-induced fluorescence in flames. Collisional quenching rates are important for the determination of species concentrations by laser-induced fluorescence. The collisional quenching lifetime following excitation of the R(2)(4) A(2)Sigma(+) (nu' = 0) ? X(2)II (nu'' = 0) transition was measured to be 1.8 nsec in the burned-gas region of an atmospheric-pressure, premixed methane-air flame.
