cds-question@unistra.fratomic-physicsAccurate, experimental rovibronic energy levels, with associated labels and uncertainties, are reported for 11 low-lying electronic states of the diatomic ^48^Ti^16^O molecule, determined using the MARVEL (Measured Active Rotational-Vibrational Energy Levels) algorithm. All levels are based on lines corresponding to critically reviewed and validated high-resolution experimental spectra taken from 24 literature sources. The transition data are in the 2-22160cm^-1^ region. Out of the 49679 measured transitions, 43885 are triplet-triplet, 5710 are singlet-singlet, and 84 are triplet-singlet transitions. A careful analysis of the resulting experimental spectroscopic network (SN) allows 48590 transitions to be validated. The transitions determine 93 vibrational band origins of ^48^Ti^16^O, including 71 triplet and 22 singlet ones. There are 276 (73) triplet-triplet (singlet-singlet) band-heads derived from Marvel experimental energies, 123(38) of which have never been assigned in low- or high-resolution experiments. The highest J value, where J stands for the total angular momentum, for which an energy level is validated is 163. The number of experimentally derived triplet and singlet ^48^Ti^16^O rovibrational energy levels is 8682 and 1882, respectively. The lists of validated lines and levels for ^48^Ti^16^O are deposited in the supporting information to this paper.2017ApJS..228...15Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/228/15CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/833/9 : Rotational frequencies of TiO isotopologues (Lincowski+, 2016)J/MNRAS/463/771 : ExoMol XVIII.
