Abstract

Gas temperatures and centrifugal distortion constants can be determined by means of a computer program which simulates the Fabry-Perot interferograms of rotational Raman spectra. This computer program takes into account the instrumental broadening factors of the Fabry-Perot interferometer along with Doppler and pressure broadening of the spectral lines. Variations in the profiles of the computed interferograms for nitrogen were studied as a function of gas temperature and centrifugal distortion constant D. Comparison with experimental interferometric data for nitrogen yielded the gas temperature and a value of the centrifugal distortion constant equal to (5.80 ± 0.23) × 10-6 cm-1.
