Abstract

Abstract: The line positions and intensities of carbon dioxide isotopologues have been retrieved in the 4681–5337 cm −1 spectral range from Fourier transform spectra of carbon dioxide recorded in LADIR (Paris, France) with the Bruker IFS 125-HR [Jacquemart D, et al., J Quant Spectrosc Radiat Transf 2012;113:961–975]. In total 6386 line positions and intensities of 89 bands of 12 isotopologues 16 O 12 C 16 O, 16 O 13 C 16 O, 16 O 12 C 18 O, 16 O 12 C 17 O, 16 O 13 C 18 O, 16 O 13 C 17 O, 18 O 12 C 18 O, 17 O 12 C 18 O, 17 O 12 C 17 O, 18 O 13 C 18 O, 17 O 13 C 18 O, and 17 O 13 C 17 O have been retrieved. 23 bands were newly assigned. All studied bands belong to the Δ P =7 series of transitions, where P = 2 V 1 + V 2 + 3 V 3 is the polyad number ( V i are vibrational quantum numbers). The accuracy of the line position measurement is about 0.3×10 −3 cm −1 for the unblended and not very weak lines. The accuracy of the line intensities varies from 4% to 15% depending on the isotopologue, on the intensity of the line and on the extent of the line overlapping. The observed intensities were used to fit the effective dipole moment parameters for the Δ P =7 series of transitions in 16 O 12 C 18 O, 16 O 12 C 17 O, 12 C 17 O2, 17 O 12 C 18 O, 16 O 13 C 17 O, 13 C 17 O2 and 17 O 13 C 18 O isotopologues of carbon dioxide. Highlights: Fourier transform spectroscopy of 17 O enriched CO2 between 4681 and 5337 cm −1 . Line parameters of 6386 transitions belonging to 89 bands are determined. Δ P =7 effective dipole moment parameters are determined for the seven CO2 isotopologues.
