Abstract: | -5 fractional absorption) and generality of IR-CRLAS for combustion studies is demonstrated for low pressure laminar flames and is shown to be robust even in sooting environments with high temperature gradients. The ability to obtain (1-D) spatially resolved spectra of both reactants and products within a narrow spectral region is also demonstrated. In these initial flame studies, two information rich mid-infrared spectral regions are probed at Doppler-limited resolution, centered about 1.5 μm and 3.3 μm. Received: 30 August 1996 |
