Starikov V.I. Vibrational dependence of the broadening coefficients of H2O absorption lines perturbed by neon, krypton, and xenon pressure. // Optika Atmosfery i Okeana. 2018. V. 31. No. 04. P. 253–262 [in Russian].
The dependence of the intermolecular interaction potentials for the H2O–Ne, H2O–Kr, and H2O–Xe systems on the vibrational quantum numbers of H2O molecule is derived. The broadening coefficients γ are calculated for seven vibrational bands ν1, ν2, ν3, 2ν2, ν1 + ν2, ν2 + ν3, and ν1 + ν2 + ν3 of H2O molecule from the region 640–9888 cm-1. The analytical formula are suggested for the calculated broadening coefficients γ at T = 296 K. It is shown that the excitation of stretching modes of the vibrations in H2O molecule increases the broadening coefficients γ. The influence of the bending vibrations on γ is insignificant.
