The electronic structure of the methylene amidogen radical, $CH2N$, has been studied using many-body perturbation theory. Optimization of the structural parameters predicts $ReCN=2.322b,ReCH=2.017$ b, and $\theta e(NCH)=122.5\circ$. Fourth-order MPPT calculations including all single and double excitation diagrams for $CH2N$ and HCN have been completed, and the results used to predict the heat-of-formation for $CH2N$.
