The dissociation of the hypothetical system N[6] into three N[2] molecules has been studied using multiconfigurational second order perturbation theory (CASSCF/CASPT2) aided by a preliminary study using the density functional (DFT) approach. A concerted transition state with C[2] symmetry has been found between the most stable linear diazide form of N[6] and three N[2] molecules. The computed barrier is 28.7 kcal/mol (CASPT2) and 17.4 kcal/mol (DFT), respectively.
