摘要：
Laser-induced fluorescence (LIF) of CF2 radicals in atmospheric diffusion flames is reported for the first time. When a CH4 flame is premixed with HCFC-22 (CClF2H) or HFC-134a (CF3CFH2), fluorescence spectra between 250 and 314 nm of the (A) over tilde(1)B(1)-(X) over tilde(1)A(1) transition from CF2 are observed when the flame is probed by a KrF laser. When these two halocarbons are added to an atmospheric H-2 flame, similar LIF spectra of CF2 are also observed. Two-dimensional LIF images from the flames show that the CF, radicals are localized between the flame center and the flame front. (C) 1998 by The Combustion Institute.
