✦ Synopsis

Infrared spectra of a carbon dioxide sample enriched with oxygen-17 have been recorded with a resolution of about 0.0025 cm-1 in the region of the laser bands near 10 and 9 µm, using the long path difference Fourier Transform Spectrometer of the LPMA in Paris. The two laser bands of the 16O12C17O and 17O12C18O species have been analyzed for the first time. Line intensities for several isotopic species have been measured in this region and the rotationless transition dipole moments and Herman-Wallis coefficients of the corresponding bands have been reported. In particular intensities, alternation in the spectra of 17O12C17O has been analyzed. Copyright 1999 Academic Press.

The effective operator approach is applied to the calculation of the line positions of two isotopic species, 16 O 12 C 17 O and 16 O 12 C 18 O, of the carbon dioxide molecule. More than 6600 observed line positions of 72 bands of 16 O 12 C 18 O selected from the literature have been used to derive 7
