Abstract

The parameters of the 190 H₂O absorption lines broadened by the carbon dioxide pressure were determined for the vibration-rotational bands ν₁+ν₃, 2ν₂+ν₃, and 2ν₁ in the 6760–7430 cm^–1 spectral region. The measurements were carried out on a Bruker HR 125 Fourier spectrometer at room temperature with a spectral resolution of 0.01 cm^–1. The values of the broadening and shift coefficients of the H₂O absorption lines are determined for the Voigt profile and the modified Voigt profile which takes into account the dependence of the broadening on the speed of the colliding molecules. The parameters of the H₂O absorption lines obtained in the work will allow more accurate determination of the H₂O concentration in the carbon dioxide atmospheres of the planets.
