cds-question@unistra.fratomic-physicsA hot line list is presented for ^12^C_2_H_4_ in its ground electronic state. This line list, called MaYTY, contains 50 billion transitions and should be complete for temperatures up to 700K. It covers the wavelengths up to 7000cm^-1^ and rotational excitation up to J=78. The line list was computed using the eigenvalues and eigenvectors of C_2_H_4_ obtained by variational solution of the Schrodinger equation for the rotation-vibration motion of nuclei employing the program TROVE and a new 'spectroscopic' potential energy surface (PES) obtained by refining an ab initio PES (CCSD(T)=F12b/cc-PVTZ) in a least-squared fit to the experimentally derived energies with J=0,1 as extracted from the literature (Georges R., Bach M., Herman M., 1999, Mol. Phys., 97, 279) and HITRAN database. The dipole transition probabilities are represented by the Einstein-A coefficients obtained using a new ab initio dipole moment surface (CCSD(T)-F12b/aug-cc-pVTZ).2018MNRAS.478.3220Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/478/3220CatalogResearchIsServedByTAP 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.
