Absolute line intensities in the ν3 band of 12CH3F by diode-laser spectroscopy

Research output: Contribution to journalArticle


Infrared absolute line intensities of the ν3 band of CH F have been measured around 9.5 μm 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 = 379.2 ± 5.9 cm · atm at 296 K) and the first Herman-Wallis factor (α = 0.35 × 10 ± 0.10 × 10 ).
