 Title: ANALYSIS OF THE FOURIER TRANSFORM SPECTRUM OF $^{13}C^{18}O_{2}$ IN THE $4.3\ \mu m$ AND $16\ \mu m$ REGIONS Creators: Reisfeld, M. J.; Flicker, H.; Goldblatt, Maxwell Issue Date: 1980 Publisher: Ohio State University Abstract: Fourier Transform spectra have been obtained for $^{13}C^{18}O_{2}$ in the regions of $\nu_{2} (16\ \mu$m) and $\nu_{3} (4.3\ \mu$m) at a resolution of $0.04 cm^{-1}$. From a least-square fit of the P and R branch lines for the transitions, values have been obtained for the molecular spectroscopic constants. Based on the derived constants, the calculated wavenumbers for the P And R branch lines for both the $(01^{1}0 - 00^{0}0)$ and $(00^{0}1 - 00^{0}0)$ transitions agree with the observed positions within $\pm 0.003$ $cm^{-1}$. We have also observed the different bands $\nu_{1} - \nu_{2}$ and $(\nu_{3} + \nu_{2}) - \nu_{2}$. From an analysts of these transitions we have obtained values for the $\ell$-doubling constant for $\nu_{2}$ and the location of the Fermi resonance levels $(100^{0}0, 02^{0}0)$.
