A correspondence between the observed electronic states of N$_2$ and CO is presented, in order to compare the perturbations and predissociations of these two isoelectronic molecules. The homogeneous perturbations between the $^1\Sigma^+$ (or $^1\Sigma_u^+$) and the $^1\Pi$ (or $^1\Pi_u$) states are reviewed, and comparisons are made between the indirect predissociations of the $^1\Pi$ states due to the $^3\Pi$ states in both N$_2$ and CO.Π
