The optical Stark spectrum of the origin bands of the $E3\Pi 0-X3\Delta 1,A3\Phi 2-X3\Delta 1$, and $B3\Pi 0-X3\Delta 1$ band systems of titanium monoxide, TiO, were analyzed to produce permanent electric dipole moments of $3.34(1)D,3.2(4)D,4.89(5)D$ and $4.9(2)D$ for the $X3\Delta 1,E3\Pi 0,A3\Phi 2$ and $B3\Pi 0$ states, respectively. The observations are compared with a simple molecular orbital description for the low-lying states and electronic structure calculations.
