Abstract

The cyanonitrene radical, NCN, is detected by laser-induced fluorescence in laminar, adiabatic, flat ϕ = 1.3 methane–air flames at 200 hPa and atmospheric pressure. Laser excitation of the A ̃ Π u 3 ( 020 ) X ̃ Σ g 3 ( 000 ) band at 317 nm allows off-resonant fluorescence to be detected at 326 nm . Excitation and dispersed fluorescence spectra are presented, as well as profiles of NCN and CH versus height above burner.
