cds-question@unistra.fratomic-physicsNitric acid is a possible biomarker in the atmospheres of exoplanets. An accurate line lists is computed for nitric acid (HNO3). This line list covers wavelenghts longer than 1.42 um (0-7000cm^-1^) and temperatures up to 500K. The line list is computed using a hybrid variational-perturbation theory and empirically tuned potential energy and dipole surfaces. It comprises almost 7 billion transitions involving rotations up to J=100. Comparisons with spectra from the HITRAN and PNNL databases demonstrate the accuracy of our calculations. Synthetic spectra of water - nitric acid mixtures suggest that nitric acid has features at 7.5 and 11.25um are capable of providing a clear signature for HNO3; the feature at 11.25um is particularly promising. Partition functions plus full line lists of transitions are made available in an electronic form as supplementary data to the article and at www.exomol.com.2015MNRAS.452.1702Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/452/1702CatalogResearchIsServedByTAP 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 PH3 (Sousa-Silva+, 2015)J/MNRAS/448/1704 : ExoMol line lists for H2CO (Al-Refaie+, 2015)J/MNRAS/449/3613 : ExoMol line lists for AlO (Patrascu+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/452/1702https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/452/1702http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/452/1702https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/452/1702https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/452/1702http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/452/1702GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/452/1702/hno3Partition function of HNO3recnoRecord number assigned by the VizieR team.
