✦ Synopsis

branches of the 5 perpendicular band. These lines with J values ranging from 1 to 23 and K from 0 to 9 (K Յ J) are located in the spectral range 1416 -1573 cm Ϫ1 . The collisional halfwidths are obtained by modeling each spectral line with a Voigt and a Rautian profile. The noncorrelated Rautian model leads to larger values of broadening coefficients than the Voigt model. These coefficients have also been calculated from a semiclassical model in which the intermolecular potential includes electrostatic, induction, and dispersion energy contributions. The results in the P, Q, and R branches of the 2 and 5 bands are in overall agreement with the experimental data.

Infrared absolute line intensities of the nu6 band of CH3F have been measured around 8.5 μm using a diode-laser spectrometer. These line strengths were obtained by the equivalent width method and, for 13 lines, by fitting a Rautian profile to the measured shape of the lines. From these results, we h

Spectrally resolved measurements of water vapor absorption spectra near \(1.4 \mu \mathrm{m}\) have been performed with a tunable, distributed-feedback InGaAsP diode laser. A lineshape analysis was used to infer the collision-broadening coefficient of 11 rovibrational transitions in the \(\nu_{1}+\n
