Abstract
The He-broadening (γ) and shift (δ) coefficients of 76 rovibrational transitions belonging to the 3ν1, 3ν3, ν1 + 2ν2 + ν3, and 2ν1 + ν3 vibrational bands of H2O molecule were measured in the spectral range between 10,200 and 11,200 cm−1 with the spectral resolution of 0.01 cm−1 using a Bruker IFS 125HR FTIR spectrometer. The calculations of γ and δ were performed in the framework of the semi-classical method. It was shown that the vibrational dependence of the long-range as well as the short-range parts of an isotropic H2O-He interaction potential influence substantially the calculated broadening coefficients γ. The vibrationally and rotationally dependent analytical model for the broadening coefficients calculation is presented and discussed.
