Photodissociation and photoisomerization pathways of the HNCN free radical

Article abstract of DOI:10.1063/1.1367411

The photodissociation dynamics of the HNCN free radical and its photofragment translational spectroscopy was done to characterize the global CH+N₂ potential energy surface. A reaction mechanism was proposed for the dissociation of HNCN to ground state. Photofragment mass distributions indicated N₂ loss to be the primary dissociation pathway. The study suggests that HNCN radical first isomerizes to a cyclic HCN₂ intermediate. The bond dissociation energy D_o and heat of formation were measured to be nearly 2.8eV and 3.35eV respectively.
