Abstract

Coaxial ion-laser beam photofragmentation spectroscopy combined with coincidence detection is a powerful method for probing doubly charged molecular ions. The high-resolution photofragmentation spectra contain detailed information on the molecular structure and dissociation dynamics od doubly charged cations. Our study on N₂²⁺ reveals detailed intramolecular interactions with other states, and also provides direct information on previously unobserved electronic states of this dication. We discuss these intramolecular interactions and the dissociation mechanism and demonstrate the high sensitivity of this technique.
