The electronic potential curves for the $X2\Sigma +,B2\Sigma +,A2\Pi$, lowest $\mathrm{<mrow\; data-mjx-texclass="ORD">4</mrow>}\Sigma +$, and lowest $\mathrm{<mrow\; data-mjx-texclass="ORD">4</mrow>}\Pi$ states of CN have been calculated. The calculation used approximately 50 configurations in an MCSCF calculation, followed by nearly 1000 configurations in a CI calculation. The dissociation energies, electronic dipole moments, allowed electronic transition moments and spectroscopic constants will be presented and compared with experiment and previous calculations where available.
