cds-question@unistra.fratomic-physicsAn accurate line list for calcium oxide is presented covering transitions between all bound ro-vibronic levels from the five lowest electronic states. The ro-vibronic energies and corresponding wavefunctions were obtained by solving the fully coupled Schroedinger equation. Ab initio potential energy, spin-orbit, and electronic angular momentum curves were refined by fitting to the experimental frequencies and experimentally derived energies available in the literature. Using our refined model and high level ab initio electric dipole moments reported previously accurate ro-vibronic energies and Einstein A coefficients were computed. Our work is the first fully coupled description of this system. Our line list is the most complete catalogue of spectroscopic transitions available for CaO and is applicable for temperatures up to at least 5000 K. CaO has yet to be observed astronomically but its transitions are characterised by being particularly strong which should facilitate its detection. The CaO line list is made available in an electronic form as supplementary data to this article and at www.exomol.com.2016MNRAS.456.4524Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/456/4524CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/425/34 : ExoMol line lists for BeH, MgH and CaH (Yadin+, 2012)J/MNRAS/434/1469 : ExoMol line lists for SiO (Barton+, 2013)J/MNRAS/437/1828 : ExoMol line list for HCN and HNC (Barber+, 2014)J/MNRAS/440/1649 : ExoMol line lists for CH4 (Yurchenko+, 2014)J/MNRAS/442/1821 : ExoMol line list for KCl (Barton+, 2014)J/MNRAS/445/1383 : ExoMol line list for phosphorus nitride (PN) (Yorke+, 2014)J/MNRAS/446/2337 : ExoMol line lists for phosphine (PH_3_) (Sousa-Silva+, 2015)J/MNRAS/448/1704 : ExoMol line lists for formaldehyde H_2_CO (Al-Refaie+, 2015)J/MNRAS/449/3613 : ExoMol line lists for AlO (Patrascu+, 2015)J/MNRAS/451/634 : ExoMol line lists for NaH and NaD (Rivlin+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/456/4524https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/456/4524http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/456/4524https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/456/4524https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/456/4524http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/456/4524GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/456/4524/caostateLabelled rovibronic statesN[1/130660] State ID, non-negative integer indexmeta.idintprimaryEState energy term value in cm-1cm**-1phys.energy;phys.atmol.leveldoublegTotal state degeneracyphys.electron.degenintJJ-quantum number J$ is the total angular momentum excluding nuclear spinmeta.number;phys.atmol.sWeight.nuclearintpar[+/-] Total parityphys.atmol.paritychare/f[e/f] e/f-rotationless-parity parityphys.atmol.paritycharStateThe label of the electronic statemeta.codecharv[0/65] Vibrational quantum numberphys.atmol.qn;phys.mol.vibrationintLambda[-1/1] Projection of the electronic angular momentumphys.atmol.qnintSigma[-1/1] Projection of the electronic spinphys.atmolintOmega[-2/2] projection of the total angular momentumphys.atmol.qnintJ/MNRAS/456/4524/caotransTransition filerecnoRecord number assigned by the VizieR team.
