dc.description.abstractBulk TiO$_{2}$ is a widely used photo-activated catalytic material, yet poorly understood. Much of the motivation for studies of molecular TiO$_{2}$ is the observation {\textbf{129}} 3022, 2007.} 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. {\textbf{676}} 1367, 2008.} 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 TiO$_{2}$ 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$^{-1}$ {\textbf{11}} 2649, 2008.}en_US
