REMPI detection of CH3 in low-pressure flames

Meier U, Kohse-Höinghaus K. REMPI detection of CH3 in low-pressure flames. Chemical Physics Letters. 1987;142(6):498-502.This study presents results on the detection of CH, in low-pressure methane-oxygen flames using resonance-enhanced multiphoton ionization (REMPI) techniques. Experiments in a discharge-flow reactor were performed for optimization purposes. Excitation wavelengths near 286 and 333 nm were examined: the former is not recommended for flame applications, although it may be preferable under flow reactor conditions
