cds-question@unistra.fratomic-physicsA variationally computed ^28^SiH_4_ rotation-vibration line list applicable for temperatures up to T=1200K is presented. The line list, called OY2T, considers transitions with rotational excitation up to J=42 in the wavenumber range 0-5000cm^-1^ (wavelengths {lambda}>2um). Just under 62.7 billion transitions have been calculated between 6.1 million energy levels. Rovibrational calculations have utilized a new 'spectroscopic' potential energy surface determined by empirical refinement to 1452 experimentally derived energy levels up to J=6, and a previously reported ab initio dipole moment surface. The temperature-dependent partition function of silane, the OY2T line list format, and the temperature dependence of the OY2T line list are discussed. Comparisons with the PNNL spectral library and other experimental sources indicate that the OY2T line list is robust and able to accurately reproduce weaker intensity features. The full line list is available from the ExoMol database and the CDS database.2017MNRAS.471.5025Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/471/5025CatalogResearchIsServedByTAP 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+, 2015J/MNRAS/448/1704 : ExoMol line lists for formaldehyde H_2_CO (Al-Refaie+, 2015J/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.
