摘要
The second overtone band of H-2-H-2 spectra at 77 K were recorded for gas densities between 350 and 1000 amg (1 amg = 44.614 981 mol/m(3)) with a 2 m stainless steel high-pressure transmission-type absorption cell. The profile analyses of these spectra were carried out using the Birnbaum-Cohen line shape function for the quadrupolar transitions and the Levine-Birnbaum line shape function for the overlap transitions. The observed spectra were modeled with synthetic profiles which are composed of the superposition of an overlap-induced and a quadrupolar-induced profile. The fitting parameters were determined from the analysis. Satisfactory agreement of the measurements with the calculated profiles is observed.
