摘要：

Infrared absolute Line intensities of the nu(3) band of (CH3F)-C-12 have been measured around 9.5 mu m using a diode-laser spectrometer. These line strengths were obtained from the equivalent width method and, for a few lines, by fitting a Rautian profile to the measured shape of the lines. From these results, we have deduced the vibrational bandstrength (S-0(v) = 379.2 +/- 5.9 cm(-2). atm(-1) at 296 K) and the first Herman-Wallis factor (alpha = 0.35 x 10(-3) +/- 0.10 x 10(-3)).
