Abstract

This paper presents results of the study of the water vapour continuum absorption within 8800 and 10600 cm^-1 absorption bands. The continuum spectra recorded at increased temperatures (398, 431, and 471 K) and pressures are discussed on the basis of water dimer model¹ supplemented by a contribution of intermediate line wings according to the model² . The values of semiempirical parameters that characterize contribution and effective spectral width of the intermediate line wings are derived from fitting to the experimental continuum absorption spectra. A preliminary analysis of the temperature and pressure dependences of the fitted parameter is performed. It is shown that a better agreement between the simulated and experimental continuum spectra can be reached both within centre and in close wings of the absorption bands when intermediate line wings are accounted according to the model² .
