A universal function is suggested for calculation of the A-broadening coefficients g of H2S absorption lines (A = He, Ne, Ar, Kr, and Xe). Only one parameter of this function depends on the broadening gas atom, while other parameters are common for all atoms. This parameter determines the ratio ν(А)/ν(А´) for A and A´ atoms. Parameters of the function are determined in the fitting procedure from the coefficients γ measured and calculated for ν1, ν2, and ν3 vibrational bands of H2S molecules. The coefficients g calculated are statistically compared with measurements. With the exception of some data for the ν1 and ν3 bands, the calculated and measured γ are in a good agreement for all collisional partners A.
