    Abstract

    The problem of calculation of He-broadening coefficients for rotational lines of the H2S molecule at different temperatures (including close to absolute zero) is considered and discussed. The parabolic and exact trajectory models are used in the calculations. It is shown that semi-classical methods allow retrieving experimental data on broadening coefficients for temperatures of up to 10 K. The optimal inter-molecular potential has been calculated, which gives the best description of the temperature dependence of He-broadening coefficients for the 110 ← 101 and 220 ← 211 rotational lines.
