The high resolution laser induced fluorescence spectrum of MgNC was recorded for the $A~2\Pi 3/2(0,0,0)-X2\Sigma 3/2+(0,0,0)$ and the $A~2\Pi 1/2(0,0,0)-X2\Sigma 1/2(0,0,0)$ band systems and optical Stark measurements were performed on the and branch features. The field free spectrum of this band system was first measured by Wright and $Millera$. The MgNC radicals were produced by the laser ablation of a magnesium rod in the presence of a acetonitrile/argon supersonic expansion. The permanent electric dipole moment, $\mu$, for $\mathrm{<mrow\; data-mjx-texclass="ORD">24</mrow>}MgNC$ was determined to be 3.116(36)D and 3.424 (103)D for the $A~2\Pi 1/2(0,0,0)$ and $X2\Sigma 1/2+(0,0,0)$ states, respectively. The analysis of the Stark measurements will be reported and a comparison of the permanent dipole moments of MgNC and $CaNCb$ will be given.
