Abstract: Measurements of N-2- and O-2-broadening of the rotational spectrum of CHF2Cl have been performed up to frequencies of 686 GHz. The pressure broadening coefficients of eight different (J + 1)(2,J-1) <-- J(1,J-1) rotational transitions have been measured and compared with semiclassical calculations. The observed decrease of the magnitude of pressure-broadening coefficients for J > 28 has been explained by considering line coupling effects which occur when the transitions (J + 1)(2,J-1) <-- J(1,J-1) completely overlap the (J + 1)(3,J-1) <-- J(2,J-1) ones.
