A universal analytical model is proposed for calculating coefficients γ of broadening of absorption lines of the H2S molecule by inert gas atoms A (helium, neon, argon, krypton, and xenon). In this model, only one parameter depends on the broadening atom A; other parameters are common for all atoms. This parameter determines the ratio γ(A)/γ(A′) for the A and A′ atoms. The model parameters are determined from values of γ calculated for the fundamental bands ν1, ν2, and ν3 of the H2S molecule, as well as from known experimental values of γ. Values of γ calculated using the model are compared with available experimental data. For some lines from the ν1 and ν3 bands, there is a significant discrepancy between the experiment and calculation.
