Ar-broadening coefficients are measured for 29 lines of CH 3 F in the R Q 0 and R Q 6 branches of the 6 band, using a tunable diode-laser spectrometer. The collisional widths obtained by fitting Rautian profiles to the measured shapes of the lines are significantly larger, especially for the overlap

H 2 -broadening coefficients have been measured for 66 rovibrational lines of NH 3 at room temperature in the P P and R P branches of the ν 4 band in the range 1470-1600 cm -1 , using a high-resolution Fourier transform spectrometer. The collisional widths are obtained by fitting Voigt profiles to t
Measurement of absorption by pure ammonia and NH 3 -(H 2 , He, and Ar) mixtures in the P branch of the ν 4 band at room temperature have been made with a high-resolution Fourier transform spectrometer. Least squares fits of the spectra using different techniques are used for the analysis of the evol
Measurements of pressure-broadening and cross-relaxation rates of rotation-inversion transitions in the n 4 band (1470-1600 cm 01 ) of NH 3 perturbed by CO 2 are reported. Pressure-broadening parameters were measured at a low pressure of CO 2 (0-180 Torr). At high pressure, the two lines of the doub
Pressure broadening ( PB) linewidths and cross-relaxation parameters have been measured in the \(v_{4}\) rovibrational band of \(\mathrm{NH}_{3}\) (window region \(1450-1600 \mathrm{~cm}^{-1}\) ) using diode laser and Fourier transform (FT) spectrometers. The measurements were performed using \(\mat
