Line intensities of 12C2H2 in the 1.3, 1.2, and 1 µm spectral regions

Abstract

Intensities of about 320 lines of the 12C2H2 molecule, belonging to 7 parallel bands, are measured in the 1.3, 1.2, and 1 µm spectral regions, with a mean accuracy around 3 or 7% depending on the spectral region. Vibrational transition dipole moment squared values and Herman-Wallis coefficients are obtained for each band, in order to model the rotational dependence of the transition dipole moment squared, except for the 1 + 3 + 240 band at 7732.78 cm1 that exhibits an unusual rotational dependence because of a strong ℓ-type resonance. HITRAN format line lists are set up for applications.
