N(2) and CO Vibrational CARS and H(2) Rotational CARS Spectroscopy of CH(4)-N(2)O Flames

Abstract

Broadband CARS (coherent anti-Stokes Raman scattering) spectra of N(2) and C0 were obtained from the post-flame gases of rich CH(4)-N(2)O flames by the use of the nonplanar BOXCARS technique. The temperature and concentration of both N(2) and CO in these flames, estimated from CARS spectra with the aid of model calculations, agreed with standard thermochemical predictions. In addition, several pure rotational H(2) CARS transitions, most of which had previously been unobserved, were seen in several spectral regions, most notably in both the CO and NO CARS regions. These observations are important in future modeling of CARS data.
