摘要：

The broadening and shift coefficients of H2O absorption lines are compared for Ar, He, H-2, and N-2 buffer gases. The broadening and shift coefficients were derived from the analysis of the absorption spectra recorded with an FTIR spectrometer in the spectral region 8650-9020 cm(-1) with a spectral resolution of 0.01 cm(-1). Using two model line profiles (Voigt and speed-dependent Voigt profiles) the parameters of the H2O absorption lines were calculated. It is shown that the speed-dependent Voigt profile provides better agreement with experimental data.
