New line intensity measurements for 12C2H2 around 7.7 µm and HITRAN format line list for applications

Abstract

Absolute intensities of 467 lines are measured in 9 bands of the 7.7 µm spectral region of the 12C2H2 molecule, with an average accuracy of 5%. For each band, the vibrational transition dipole moment squared and Herman-Wallis coefficients are obtained in order to model the rotational dependence of the transition dipole moment squared. These results are used to calculate a line list for atmospheric or astrophysical applications. Merged in the line list set up in a previous work for the 8 strongest bands around 7.7 µm [Gomez et al. Line intensities of 12C2H2 in the 7.7 µm spectral region. JQSRT, in press, http://dx.doi.org/10.1016/j.jqsrt.2009.05.018], these new data give now a quasi-exhaustive view of the 12C2H2 spectrum in the involved spectral region.
