High-resolution lineshapes of the HF P(3) and P( 6) transitions (2-0 band) have been recorded in a 14.9-cm long absorption cell (T Ο 296 K) using a pair of (InGaAsP)-distributed feedback diode lasers operating near 1.31 and 1.34 m, respectively. The absorption lineshapes were least-squares fit to Vo
He-broadening coefficients are measured for 28 lines of 12 branches of the n 6 band, using a tunable diode laser spectrometer. The collisional widths obtained by fitting Rautian profiles to the measured shapes of the lines are slightly larger than those derived from Voigt profiles. The broadening c
