Two-body dissociative charge exchange dynamics of sym-triazine.
Translational spectroscopy coupled with coincidence detection techniques has been used to investigate the two-body dissociation of sym-triazine to HCN + (HCN)2 upon electronic excitation from charge exchange between the sym-triazine cation and cesium. This dissociation mechanism was determined to occur after excitation of sym-triazine into the 3s Rydberg electronic manifold, and the observed dynamics suggest that the mechanism competes with a stepwise three-body dissociation mechanism to three HCN products that occurs from this same electronic excitation. On the basis of reported stabilization energies of several isomers of the HCN dimer, possible structures of the metastable (HCN)2 species are discussed in light of the current measurements.
