Abstrakt: Measurements are presented of the relative density profiles of formyl and methyl radicals in stoichiometric methane/oxygen and ethylene/oxygen flames which exemplify recent progress in the use of resonance-enhanced multiphoton ionization (REMPI) spectroscopy for flame diagnostics. The advantages and present limitations of this new laser-based technique are discussed. The high sensitivity of the REMPI method for the detection of HCO presents an opportunity for better measurements of flame profiles and of the rate constants for consumption of this important intermediate in hydrocarbon combustion.
