cds-question@unistra.frastronomical-modelsstellar-atmospheresinfrared-astronomyspectroscopyultraviolet-astronomyA computed line list for formaldehyde, H_2_^12^C^16^O, applicable to temperatures up to T=1500K is presented. An empirical potential energy and ab initio dipole moment surfaces are used as the input to nuclear motion program TROVE. The resulting line list, referred to as AYTY, contains 10.3 million rotational-vibrational states and around 10 billion transition frequencies. Each transition includes associated Einstein- A coefficients and absolute transition intensities, for wavenumbers below 10000cm^-1^ and rotational excitations up to J=70. Room-temperature spectra are compared with laboratory measurements and data currently available in the HITRAN database. These spectra show excellent agreement with experimental spectra and highlight the gaps and limitations of the HITRAN data. The full line list is available from the CDS database as well as at www.exomol.com.2015MNRAS.448.1704Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/448/1704CatalogResearchIsServedByTAP 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 PN (Yorke+, 2014)J/MNRAS/446/2337 : ExoMol line lists for PH3 (Sousa-Silva+, 2015)J/MNRAS/449/3613 : ExoMol line lists for AlO (Patrascu+, 2015)J/MNRAS/451/5153 : 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/448/1704https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/448/1704http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/448/1704https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/448/1704https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/448/1704http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/448/1704GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapUVInfrareddefaultJ/MNRAS/448/1704/h2co_0-70labelled rovibrational statesK[0/70] Projection of J on z-axismeta.noteinti[1/10296998] State ID, non-negative integer index, starting at 1meta.idlongprimaryE[0/25125] State energy term value in cm^-1^cm**-1phys.energy;phys.atmol.leveldoubleg[1/423] Total state degeneracyphys.electron.degenintJ[0/70] J-quantum number, total angular momentum excluding nuclear spinmeta.numberintG[1/4] Total symmetry {Gamma} (1)phys.atmol.parityintv1[0/10] normal mode vibrational quantum numberphys.mol.qnintv2[0/16] normal mode vibrational quantum numberphys.mol.qnintv3[0/11] normal mode vibrational quantum numberphys.mol.qnintv4[0/16] normal mode vibrational quantum numberphys.mol.qnintv5[0/10] normal mode vibrational quantum numberphys.mol.qnintv6[0/16] normal mode vibrational quantum numberphys.mol.qnintGv[1/4] Vibrational symmetry {Gamma}_viv_ (1)phys.atmol.parityintGr[0/4] Rotational symmetry {Gamma}_rot_ (1)phys.atmol.parityintN(Bl)[1/67238] Reference number in the polyadmeta.id;meta.mainintC2[0/1] Square of the largest coefficientmeta.notefloatn1[0/11] Local mode vibrational quantum numberphys.atmol.qnintn2[0/10] Local mode vibrational quantum numberphys.atmol.qnintn3[0/10] Local mode vibrational quantum numberphys.atmol.qnintn4[0/16] Local mode vibrational quantum numberphys.atmol.qnintn5[0/16] Local mode vibrational quantum numberphys.atmol.qnintn6[0/16] Local mode vibrational quantum numberphys.atmol.qnint
