    Abstract

    The theory of the spectrum shape relaxation parameters taking into account induced by collisions line mixing effects has been used for analyzing the rotational spectral lines of symmetric top molecules broadening. The calculations of the broadening coefficients and the relaxation parameters of the singlet and doublet lines of some symmetric top molecules were carried out and the results were compared with the available experimental data. It is found the line mixing effects may practically be ignored in the singlets broadening, but they are very important in the doublets broadening.
