Paper Abstract

We report new models for the absorption, excitation, and fluorescence spectra for excitations within both the A $IMP X (0,0) band of NO and the B $IMP X bands of O2 together with supporting measurements obtained from the burned regions of flames operated in pressure from 1 to 10 atm. As developed through these models, a strategy appropriate for imaging planar laser-induced fluorescence is proposed that, for lean combustion environments, would afford sensitive, single-shot measurements of NO concentration despite the photolytic interference from O2 that intensifies with increasing pressure and temperature.
