title: Infrared Fundamental and First Hot Bands of O12C17O Isotopic Variants of Carbon Dioxide.
abstract: Infrared spectra of 16O12C17O, 17O12C17O, and 17O12C18O in a carbon dioxide sample enriched with oxygen-17 have been recorded with a resolution of about 0.0025 cm-1 in the regions of the fundamental bands, nu2 (600-800 cm-1) and nu3 (2200-2400 cm-1), and in the region of the "forbidden" band, nu1 (1200-1400 cm-1), using the long path difference Fourier transform spectrometer of the LPMA in Paris. For each species, the first hot band in the 4.5-µm region and two hot bands at least in the 15-µm region have been studied for the first time, and a simultaneous reduction of wavenumbers measured in different spectral regions has been carried out yielding new or improved spectroscopic constants. Line intensities have been measured in the region of the nu2 and nu3 bands of 16O12C17O, and the corresponding rotationless transition dipole moments and Herman-Wallis coefficients have been reported.
