Line parameters measurements and modeling for the ν6 band of CH3F: Generation of a complete line list for atmospheric databases

The 8.5 mu m-spectral region of methyl fluoride was studied in terms of line positions, intensities and self-broadening coefficients at room temperature. A multispectrum fitting was used to retrieve from 7 high-resolution Fourier transform spectra line parameters for 787 transitions belonging to the nu(6) band between 1078 and 1240 cm(-1). The accuracy of line intensities and widths measurements were estimated to be around 5% and 5-10% respectively. J- and K-rotational dependences of the transition dipole moment squared and the self-broadening coefficients were observed and modeled from the measurements. A complete line list of almost 1500 transitions was generated for atmospheric or industrial detection of CH3F. Comparisons with previous studies from the literature were also performed.
