Two- and three-body photodissociation of gas phase I(-)(3)

The photodissociation dynamics of gas phase I-3 by using a fast beam photofragment translational spectrometer was examined. It was stated that the photofragment translational spectrometer was coupled to a coincidence imaging detector that enabled the direct detection and analysis of two and three neutron or anion fragments from single dissociation events. The three-body dissociation yielding I-+2I(2P3/2) photofragments was also seen throughout the energy range probed. Analysis shows that the three-body decay dynamics was dominated by synchronous concerted dissociation.Alexandra A. Hoops, Jason R. Gascooke, Ann Elise Faulhaber, Kathryn E. Kautzman, and Daniel M.
