Paper Abstract

Halfwidths and lineshifts of water vapour by Ar pressure were calculated in the framework of semiclassical broadening theory. Anisotropic and isotropic parts of polarization interactions are taken into account, when relaxation parameters are calculated. H20 mean polarizability in 301 vibrational state was determined earlier using the measured linesfifts. H20 polarizability z-component in 301 vibrational state was determined using the measured lineshifts in this work at the first time. The calculated relaxation parameters were in a good agreement with the measured one. Halfwidths and lineshifts temperature dependence is calculated within the interval 100-800 K.
