Dissociative Ionization and Coulomb Explosion of CHBrCl2 in Intense Near-Infrared Femtosecond Laser Fields

We experimentally demonstrate the dissociative photoionization of CHBrCl2 molecules in a femtosecond laser field by time-of-flight mass spectrum and dc-slice imaging technology. The results suggest that low kinetic energy components are from ionization process single-charged molecular ions. angular distribution fragment Cl+ ions can be attributed to features state configuration, Br+ electronic wave-packet evolution combination multi-dissociation processes. high Coulomb explosion multi-charged ions, error C-Br distance involved explained movement effective charge center polyatomic molecule.
