Abstract:

The results of calculations of He-broadening coefficients of the rotational lines of H2S molecule at low temperatures are presented and discussed. The parabolic and exact trajectory models are used in the calculations. It is shown that the He-broadening coefficients of H2S lines measured at up to 10ºK may be described in the framework of semi-classical methods. The optimal inter-molecular potential, which gives the best description of the temperature dependence of He-broadening coefficients of two rotational lines 110←101 and 220←211, is found in the calculations.
