The two-body dissociation of the dications formed after double ionization smallest conjugated diene, 1,3-butadiene, C4H6, is studied using coincidence time-of-flight technique and quantum chemistry calculations. dication was by ion-impact energetic Xe3+ projectiles. Our results show that butadiene has a high propensity neutral particle emission (H/H2/C2H2) prior to leading two singly charged fragments. asymmetric breakup, fragments from parent dication, observed be ≈200% more likely than...

We report on the direct experimental evidence of hydrogen migration in triply charged acetylene. The roaming atom a molecular ion is counter intuitive. three body breakup channel C2H23+→H++C++CH+ studied using technique recoil momentum spectroscopy. was generated collisions neutral parent with slow highly Xe9+ ion. Three different dissociation pathways have been identified and separated, namely, concerted an acetylene configuration, vinylidene sequential via [C2H]2+ intermediate, branching...
The three-body breakup of [C2H2]3+ formed in collision with Xe9+ moving at 0.5 atomic units velocity is studied by using recoil ion momentum spectroscopy. Three-body channels leading to (H+, C+, CH+) and H+, C2+) fragments are observed the experiment their kinetic energy release measured. into occurs via concerted sequential modes, whereas shows only mode. By collecting events coming exclusively from CH+), we have determined for unimolecular fragmentation molecular intermediate, [C2H]2+. ab...
