Line intensities of 12C2H2 in the 7.7 µm spectral region

Abstract

Absolute intensities of 414 lines are measured in eight bands of the 7.7 µm spectral region of the 12C2H2 molecule, with an average accuracy of 5%. Vibrational transition dipole moment squared values and empirical Herman-Wallis coefficients are obtained in order to model the rotational dependence of the transition dipole moment squared, except for some forbidden bands for which smoothed values are given. These data are used to calculate a line list for atmospheric or astrophysical applications.
