 Title: LINE POSITIONS AND INTENSITIES OF THE $2\nu_{2}, \nu_{1}$ AND $\nu_{3}$ BANDS OF $H_{2}^{18}O$ AND $H_{2}^{17}+O$ Creators: Flaud, J.- M.; Camy-Peyret, C.; Toth, R. A. Issue Date: 1980 Publisher: Ohio State University Abstract: From enriched $H_{2}{^{18}}O$ and $H_{2}{^{17}}O$ spectra recorded at the Jet Propulsion Laboratory with a grating spectrometer, reliable rotational energy levels of the (020), (100) and (001) vibrational states have been obtained. For each isotope a fit of these levels taking into account the Fermi and Coriolis type interactions has been performed leading to rotational and coupling constants very similar to those of $H_{2}{^{16}}O$. These fits are very satisfactory since for 85% of the levels, the difference |OBS-CALC| is less than $15\times 10^{-3}$ $cm^{-1}$. Moreover, a large number of line intensities have been measured with a relative precision of about 8%. They have been fitted using the method already, applied to $H_{2}{^{16}} O$ [J.-M. FLAUD et al., J. Mol. Specros. 55, 278 (1975)]. A comparison is given between the results obtained for the three isotopes.
