TL;DR: The current version of the GEISA-97 database is described in this paper, which contains 1,346,266 entries and includes a catalog of absorption cross-sections of molecules such as chlorofluorocarbons which exhibit unresolvable spectra.
Abstract: The current version GEISA-97 of the computer-accessible database system GEISA (Gestion et Etude des Informations Spectroscopiques Atmospheriques: Management and Study of Atmospheric Spectroscopic Information) is described. This catalogue contains 1,346,266 entries. These are spectroscopic parameters required to describe adequately the individual spectral lines belonging to 42 molecules (96 isotopic species) and located between 0 and 22,656 cm-1. The featured molecules are of interest in studies of the terrestrial as well as the other planetary atmospheres, especially those of the Giant Planets. GEISA-97 contains also a catalog of absorption cross-sections of molecules such as chlorofluorocarbons which exhibit unresolvable spectra. The modifications and improvements made to the earlier edition (GEISA-92) and the data management software are described. GEISA-97 and the associated management software are accessible from the ARA/LMD (Laboratoire de Meteorologie Dynamique du CNRS, France) web site: http://ara01.polytechnique.fr/registration.

TL;DR: In this article, Fourier transform spectra of 18 O-enriched, 17 O-enhanced, and natural water vapor recorded between 9600 and 11,400 cm -1 have been analyzed to assign the H 2 17 O spectral lines.
Abstract: Fourier transform spectra of 18 O-enriched, 17 O-enriched, and natural water vapor recorded between 9600 and 11 400 cm -1 have been analyzed to assign the H 2 17 O spectral lines. More than 1000 transitions were finally assigned to the H 2 17 O isotopic species leading to 420 precise experimental energy levels of the (0 0 3), (2 0 1), (1 2 1), (1 0 2), (3 0 0), (2 2 0) vibrational states. Rotational, centrifugal distortion, and resonance coupling parameters have been derived from the fit of the experimental energy levels to an effective Hamiltonian based on Pade–Borel approximants well suited to describe the large centrifugal distortion in H 2 O. The resulting rms deviation is 0.013 cm -1 with 97 varied parameters.
