H-broadening coefficients have been measured for 34 absorption lines of hydrogen cyanide (HCN) in the P, Q, and R branches of the v band, using a tunable diode-laser spectrometer. These lines with J values ranging from 2 to 26 are located in the spectral range 658-780 cm. The collisional widths are obtained by modeling each spectral line with a Voigt and a Rautian profile. A semiclassical calculation of these collisional broadening provides results in satisfactory overall agreement with the experimental data in the P and R branches as well as in the Q branch.
