Time-Resolved Photoion Spectroscopy of a UV-Induced Ring-Opening and Dissociation Reaction

POSTER

Abstract

We report the results of an experiment studying the UV-induced ring-opening and subsequent unimolecular dissociation of a heterocyclic ring molecule using time-resolved photoion and photoelectron spectroscopy at a seeded free-electron laser. Photoions and photoelectrons were recorded simultaneously using a covariance magnetic bottle spectrometer. The photoelectrons primarily monitor the ultrafast electronic excitation and de-excitation pathways, while the time-resolved fragment ion yields trace subsequent dissociation dynamics of the excited reaction products.
