Three-body dissociation dynamics of (SO 2) 3 studied through dissociative photodetachment of (SO 2) 3−

Abstract

The dissociative photodetachment dynamics of (SO 2) 3 − were studied by photoelectron–photofragment coincidence spectroscopy at 258 nm. Correlation between the photoelectron and photofragment translational energies was observed as previously seen in the dimer system, implying the presence of a dimer core. The three-body dissociation dynamics of (SO 2) 3 after photodetachment are consistent with a dimer core solvated by a spectator SO 2 molecule with a broad distribution in initial geometry.
