 Title: THE $4\nu_{2}$ BAND OF $H_{2}^{16}O$ Creators: Camy-Peyret, C.; Flaud, J.- M.; Maillard, J.- P. Issue Date: 1980 Publisher: Ohio State University Abstract: The $4\nu_{2}$ band of water vapor has been observed for the first time using a heated cell associated with a Fourier transform spectrometer. About 30 lines of this band have been assigned and the band center $4\nu_{2} = 6134.030 \pm 0.012 cm^{-1}$ together with the rotational constants of the (040) vibrational state have been obtained. Large intensity anomalies are present: only the P branch appears whereas the Q and R branches are almost invisible. Some line intensities have been estimated leading to a total band intensity $S_{v}(4\nu_{2}) = 0.189 \times 10^{-22} cm^{-1}/molecule.cm^{-2}\ at \ 296\ k$ Description: Author Institution: URI: http://hdl.handle.net/1811/11242 Other Identifiers: 1980-RA-5
