Line positions and absolute intensities in the laser bands of carbon-12 oxygen-17 isotopic species of carbon dioxide

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 mu m, using the long path difference Fourier Transform Spectrometer of the LPMA in Paris. The two laser bands of the (OCO)-O-16-C-12-O-17 and (OCO)-O-17-C-12-O-18 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 (OCO)-O-17-C-12-O-17 has been analyzed. (C) 1999 Academic Press.
