Absorption spectra of 12C 16O 2 and 13C 16O 2 near 1.05 μm

Abstract

The absolute line intensities of the Fermi triad 2003 i–00001 ( i = 1, 2, 3) of 12C 16O 2 and 13C 16O 2 isotopic species of carbon dioxide were retrieved from Fourier-transform spectra recorded at Doppler limited resolution in the region 9200–9700 cm −1. The accuracy of the line intensity determination is estimated to be better than 15% for most lines. 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 method have been performed. The fitting results reproduce the data within experimental uncertainty.
