cds-question@unistra.fratomic-physicsThe chloroniumyl cation, HCl^+^, has been recently identified in space from Herschel's spectra. A joint analysis of extensive vis-UV spectroscopy emission data together with a few high-resolution and high-accuracy millimeter-wave data provided the necessary rest frequencies to support the astronomical identification. Nevertheless, the analysis did not include any infrared (IR) vibration-rotation data. Furthermore, with the end of the Herschel mission, IR observations from the ground may be one of the few available means to further study this ion in space. In this work, we provide a set of accurate rovibrational transition wavenumbers, as well as a new and improved global fit of vis-UV, IR, and millimeter-wave spectroscopy laboratory data, that will aid in future studies of this molecule.2016ApJ...833L..32Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/833/L32CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/783/L5 : Ro-vibration transitions of the protonated argon ionhttp://spec.jpl.nasa.gov/ftp/pub/catalog/catdir.html : JPL molecular spectro.https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/833/L32https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/833/L32http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/833/L32https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/833/L32https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/833/L32http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/833/L32GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJ/833/L32/table1Quantum number assignments, observed and calculated wavenumbers and their differences for the v=1-0 band of HCl^+^ in the ground electronic staterecnoRecord number assigned by the VizieR team.
