Features of the methyl chloride isotopes 12CH3 35Cl, 12CH3 37Cl rotational transitions broadening, associated with the hyperfine splitting of levels due to the nuclear quadrupole interaction, are considered in the framework of impact approximation. The relaxation parameters are calculated and the values of the broadening coefficients are compared with experimental data. The character of the doublet transition contour shape transformation by pressure is investigated.
