Abstract

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 R₂(4) A²Σ⁺ (υ′ = 0) ← X²Π (υ″ = 0) transition was measured to be 1.8 nsec in the burned-gas region of an atmospheric-pressure, premixed methane–air flame.
