Laser-induced fluorescence of NCN in low and atmospheric pressure flames.
The cyanonitrene radical, NCN, is detected by laser-induced fluorescence in laminar, adiabatic, flat phi=1.3 methane-air flames at 200 hPa and atmospheric pressure. Laser excitation of the A approximately 3Piu(020)-X approximately 3Sigmag-(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.
