The high resolution laser induced fluorescence spectrum of TiS was recorded for the $C3\Delta -X3\Delta$ transition and optical Stark measurements were performed on the $R1(1),Q1(1)$, and $P1(2)$ branch features. The TiS radicals were produced by the laser ablation of a titanium rod in the presence of a supersonic expansion of $CS2$ and Ar. The $C3\Delta -X3\Delta$ spectrum was fit to within reasonable agreement with the parameters determined by Jonsson and $Launilaa$. The analysis of the Stark measurements will be reported and a comparison with the values for the permanent electric dipole moment of the isovalent $TiOb$ will be given.
