Line Intensities in the nu6 Band of CH3F at 8.5 μm
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.
