Summary:Title screen
The water vapor line broadening γ and shift δ coefficients in the ν1 + ν2, ν2 + ν3, ν1 + ν3, 2ν3, 2ν1, 2ν2 + ν3, and ν1 + 2ν2 vibrational bands were obtained from the analysis of the H2O-He absorption spectra, recorded in the region from 5000 to 7500 cm−1 with the spectral resolution of 0.01 cm−1 using a Bruker IFS 125HR FTIR spectrometer. The vibrational bands 2ν3 and ν1 + 2ν2 were investigated for the first time. The calculations ofγ and δ were performed in the framework of the semi-classical method. The rotational contributions as well as the contributions connected with the accidental resonances were taken into account in the used H2O-He interaction potential. The analytical representation of the broadening coefficients γ at planetary temperatures was introduced and discussed.
