Dispersed fluorescence spectroscopy of RuC in a supersonic expansion has allowed for the first observation of the $2\delta 312\sigma 1,1\Delta 2$ state. This work has also aided in confirming assignments of states from the $2\delta 36\pi 1$ configuration that were observed $previouslya$. Vibrational progressions were observed in the $2\delta 4,X1\Sigma +;2\delta 312\sigma 1,[0.1]3\Delta 3;[0.9]3\Delta 2$ and $[5.7]1\Delta 2$ states. Derived $\omega t\delta$ values for the $X1\Sigma +$ and $[5.7]1\Delta 2$ states of $1102.18\pm 4.68cm-1$ and $1068\pm 10cm-1$, respectively, were also determined.
