cds-question@unistra.fratomic-physicsA computed list of H2O infra-red transition frequencies and intensities is presented. The list, BT2 was produced using a discrete variable representation two-step approach for solving the rotation-vibration nuclear motions. It is the most complete water line list in existence, comprising over 500 million transitions (65% more than any other list) and is also the most accurate (over 90% of all experimental levels are within 0.3cm^-1^ of the BT2 values). Its accuracy has been confirmed by extensive testing against astronomical and laboratory data. The line list has been used to identify water lines in a variety of objects including: comets, sunspots, a brown dwarf and the nova-like object V838 Mon. Comparison of the observed intensities with those generated by BT2 enables physical values to be derived for these objects. The line list can also be used to provide an opacity for models of the atmospheres of M-dwarf stars and assign previously unknown water lines in laboratory spectra.2006MNRAS.368.1087Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/VI/119CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/121 : Energy level list and linelist of HCN/HNC (Harris+, 2006)VI/127 : High accuracy line list of HDO (Voronin+; 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VI/119https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VI/119http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VI/119https://vizier.cds.unistra.fr/viz-bin/votable?-source=VI/119https://vizier.iucaa.in/viz-bin/votable?-source=VI/119http://vizieridia.saao.ac.za/viz-bin/votable?-source=VI/119GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultVI/119/levelsFile containing the 221,097 energy levels (some with ro-vibrational assignments).
