Résumé

The self-broadening coefficients and the linestrengths of 30 lines in the ν and ν fundamental bands of CHF have been measured at high resolution in the range 1417-1553 cm, using a tunable diode-laser spectrometer. The lineshape parameters were obtained by fitting noncorrelated Galatry and Rautian profiles to the measured shapes of the lines. Both models show good agreement between the self-broadening coefficients derived from the spectra at "low" pressure (0.4 to 3 mbar) and those recorded at "high" pressure (6 to 18 mbar), but feature an overestimation of the dynamical friction parameter. A semiclassical calculation of the self-broadening coefficients, performed by using the main electrostatic interactions only, has provided larger results than the experimental data,
