 Title: VIBRATION-ROTATION SPECTRUM OF $D_{2}O$ IN THE $\nu_{3}$ REGION Creators: Gupta, V. D.; Margolis, J. S.; Brown, L. R.; Toth, R. A.; Brault, J. W. Issue Date: 1978 Publisher: Ohio State University Abstract: The high resolution rotation-vibration spectrum of $D_{2}O$ has been obtained in the region 2600 to $3000\;cm^{-1}$. The one meter Fourier transform spectrometer of the solar telescope at the Kitt Peak National Observatory in Tucson was used with a 25 cm cell at 3 Torr pressure and at room temperature. The spectral resolution is $0.01\;cm^{-1}$. Allowed and forbidden transitions have been assigned to the $\nu_{3}$ fundamental band for $J \leq 12$ and $K \leq 5$. The ground state energies of Steenbeckeliers and J. $Bellet^{1}$ are in general agreement with the observed combination differences formed from the assigned transitions. Upper state constants of the Watson Hamiltonian for the $\nu_{3}$ band have been determined from a nonlinear Least squares fit using the ground state constants. Description: $^{1}$G.
