Study of acetylene diluted in xenon by diode-laser spectroscopy: I. Temperature dependence of the broadening coefficients

Résultats de recherche: Contribution à un journal/une revueArticle

Résumé

In this paper, we present the Xe-broadening coefficients of 18 rovibrational lines in the ν4 + ν5 band of C212H2 (near 1330cm-1) determined at five temperatures, ranging from 173.2K to 298.2K. The measurement of these coefficients was realized with a tunable diode-laser spectrometer. A low temperature cell was coupled with the spectrometer in order to determine their temperature dependence. The line parameters were obtained by fitting the experimental profiles by the Voigt lineshape and the Rautian and the Galatry models, which take into account the collisional narrowing. The results were compared with previous experimental data reporting for other vibrational bands and agree with them. This indicates that they are insensitive to vibrational excitation.
