Abstract
Room temperature absorption spectra of 13C- and 18o-enriched carbon dioxide have been analyzed in the $2395-2760 cm^{-1}$ spectral region. The data used in the analysis were recorded at low pressure ( 1 Torr) and $0.01-cm^{-1}$ resolution with the Fourier transform spectrometer in the McMath solar telescope facility on Kitt Peak. Accurate positions and absolute intensities for over 900 unblended lines belonging to 11 bands of $^{16}o^{13}o^{18}o, ^{16}o^{13}o^{17}o, ^{16}o^{12}o^{18}o$ and $^{12}C^{16}o_{2}$ have been determined using a nonlinear least-square spectral fitting technique. For each band, the measured line positions were fited to determine the band center and effective upper- and lower-state rotational constants and the absolute line intensities were fitted to determine the vibrational band intensity and F-factor coefficients. These results will be reported and compared with values available in the literature.
