PARAMETRIC DECONVOLUTION METHOD - APPLICATION TO 2 BANDS OF N2O IN 1.9-MU-M REGION

A simple deconvolution method, intended for the analysis of moderately dense spectra is presented and its practical setting up discussed. The method has been first tested on synthetic lines that simulated the distortion of a Lorentz profile by a Gaussian distribution. Conditions and limits of applicability of the procedure have been investigated. The procedure has been used to study, at pressure less than 1 atm, the 40°0-00°0 and 32°0-00°0 transitions of N2O near 1.9 μm. Line strengths and self-broadened linewidths have been accurately measured and the data were used to obtain the vibrational band intensities and the pure vibrational transition moment for both transitions. The results for the transition moments are respectively 1.212 × 10-3 and 1.201 × 10-3 D for the 40°0-00°0 and 32°0-00°0 transitions. © 1978.
