Foreign gas effects were measured for the rovibrational lines of \(\mathrm{NH}_{3}\) in the \(\nu_{2}\) band with \(\mathrm{O}_{2}\), \(\mathrm{N}_{2}\), and air as perturbers, using a high-resolution FTIR spectrometer. The observed line profiles were analyzed by the Voigt-type line profile function
The concentration profiles of NH and OH were measured in an atmospheric pressure, premixed, laminar CH4/N20 flame over a porous-plug, flat flame burner. Relative profiles were obtained by laser excited fluorescence tor both compounds and normalized by laser absorption at a single point for NH. The O
