cds-question@unistra.fratomic-physicsLine lists for magnesium oxide are computed and extensive comparisons are made with existing experimental spectra. The LiTY line lists cover all ro-vibration transitions within the five lowest-lying electronic states (X, a, A, B, b) and five isotopologues ^24^Mg^16^O, ^25^Mg^16^O, ^26^Mg^16^O, ^24^Mg^17^O, ^24^Mg^18^O. The calculation use potential energy cures, spin-orbit and electronic angular momentum couplings curves determined by fitting to empirical energy levels which are reproduced to within 0.01cm^-1^ in most cases. The computed wavefunctions combined with ab initio dipole moment curves giving transition intensities and excited state radiative lifetimes which are compared with laboratory measurements. The ^24^Mg^16^O line list comprises 186842 (J<=320) ro-vibronic states and 72833173 transitions with for angular momenta, J, up to 300 and covering energies in wavenumber up to 33000cm^-1^. The line list are suitable for temperatures up to about 5000K. They are relevant to astrophysical studies of exoplanet atmospheres, cool stars and brown drafts.2019MNRAS.486.2351Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/486/2351CatalogResearchIsServedByTAP 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)J/MNRAS/452/1702 : ExoMol line lists for HNO3 (Pavlyuchko+, 2015)J/MNRAS/454/1931 : ExoMol line lists for CS isotopologues (Paulose+, 2015)J/MNRAS/456/4524 : ExoMol line lists for CaO (Yurchenko+, 2016)J/MNRAS/459/3890 : ExoMol line lists for SO2 (Underwood+, 2016)J/MNRAS/461/1012 : ExoMol line lists for H216O2 (Al-Refaie+, 2016)J/MNRAS/462/4300 : ExoMol XVII: SO3 (Underwood+, 2016)J/MNRAS/463/771 : ExoMol.
