Fourier transform spectra have been obtained at 296 K at a resolution of 0.002 or 0.004 cm -1 depending on the pressure range. Line positions and intensities of CH 3 79 Br and CH 3 81 Br belonging to the fundamental band ν 6 were measured and analyzed between 890 and 1080 cm -1 . A total of 2896 (28

✦ Synopsis
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 have deduced the vibrational band strength to be S0v = 9.66 +/- 0.13 cm-2 atm-1 at 296 K and the first Herman-Wallis factors.

Strengths of individual lines in the \(\nu_{6}\) degenerate fundamental at \(10 \mu \mathrm{m}\) of methyl chloride have been measured at room temperature using a diode laser spectrometer. From these measurements we have determined by a linearized fit two significant intensity parameters, namely, th
