Broadening and shift coefficients for H2O – H2 system in 4000 – 9000 cm–1 infrared spectral region

Water is one from major compounds in the predominantly H2 atmospheres of stars, brown dwarfs and planets. A knowledge of spectral line shapes as a function of pressure is important to interpreting remote sensing spectroscopy measurements of the atmospheres of stars and planets in wide spectral region and for models of radiative transport in these atmospheres. At present the experimental and theoretical hydrogen – broadening coefficients of H2O transitions in different spectral regions have been obtained in [1–6]. In this work we have obtained the broadening parameters for H2OH2 system in 4000-9000 cm.
