Effects of hyperfine splitting of levels in the pressure broadening of the methyl chloride rotational transitions

Abstract

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.
