Absolute line intensities of 13C 16O 2 in the 4200–8500 cm −1 region

Abstract

The absolute line intensities of 13C 16O 2 were retrieved from Fourier-transform spectra recorded in the region 4200–8500 cm −1. The accuracy of the line intensity determination is estimated to be 5% or better for most lines and about 10% for weak ones. The vibrational transition dipole moments squared and Herman–Wallis coefficients have been determined. The global fittings of the observed line intensities within the framework of the effective operators approach have been performed. As the result of the fittings, most line intensities are reproduced within the experimental accuracy. The comparison between the new measured data and the HITRAN database are also carried out.
