The Lorentz parameter Δν has been obtained by the equivalent-width method for the pressure-broadened spectral lines of low-<i>J</i> value in the HF fundamental. These values have been compared with values obtained directly from the line shapes after correction for the effect of instrumental broadening. From the line intensities <i>I</i><sub>0</sub><sup>1</sup>(<i>m</i>), the square of the matrix element of the electric dipole moment for a nonrotating anharmonic oscillator |<i>R</i><sub>0</sub><sup>1</sup>|<sup>2</sup>, and a set of rotational-correction factors <i>F</i><sub>0</sub><sup>1</sup>(<i>m</i>) have been calculated. The effective charge <i>M</i><sub>1</sub> and the vibration-rotation interaction constant θ have been calculated. Experimental and theoretical values of the <i>F</i><sub>0</sub><sup>1</sup>(<i>m</i>) have been compared.
