Bulk TiO2 is a widely used photo-activated catalytic material, yet poorly understood. Much of the motivation for studies of molecular TiO2 is the observation that there is a smooth correlation of the molecular electronic states to the band gap of the bulk. The field-free energy levels of the ground state of the monomer have been fully characterized by microwave spectroscopy. Here we report on the visible spectrum in the region between 18200 cm-1 to 18750 cm-1 of a cold molecular beam sample of TiO2 using laser induced fluorescence detection and mass-selected REMPI. Bands at 18240 cm-1, 18411 cm-1 and 18470 cm-1 were recorded at a resolution of 40 MHz and rotationally analyzed. The dispersed fluorescence of 18411 cm-1 and 18470 cm-1 bands were analyzed to produce a set of vibrational parameters for the ground state. The optical Stark spectra of the 18411 cm-1 and 18470 cm-1 bands were recorded and analyzed to determine permanent electric dipole moments and compared with the results for the band at 18655 cm-1.
