Detection of the Methyl Radical in a Methane/Air Diffusion Flame by Multiphoton Ionization Spectroscopy

Published

Author(s)

K C. Smyth, P. H. Taylor

Abstract

Methyl radicals have been detected in an atmospheric pressure, methane/air diffusion flame by three-photon ionization. The origin band of the transition between the X^2A2ground electronic state and the 3p2A2 Rydberg state is observed at 333.5 nm via two-photon excitation. A second peak BL 340.8 nm is likely due to both a methyl radical hot band in the same electronic transition and three-photon ionization or arbor atoms produced by photolysis. Spatial profiles are presented as a function of height above the burner and are discussed in terms of resonant and non-resonant ionization processes.
