The molecular beam optical LIF spectrum of the $B2\Sigma -X2\Sigma +$ band system of scandium monosulfide, ScS, has been recorded. The branch features associated with the low rotational levels were also recorded in the presence of a static electric held. The spectra were analyzed to produce magnetic hypefine parameters and permanent electric dipole moments. Comparisons with the theoretical predictions of Bauschlicher and $Langhoffg$, and experimentally determined values for $SeO4$ are made.
