Real Time Observation of a Roaming Reaction: Using Extreme Ultraviolet Pulses in a Time-Resolved Photoelectron Spectroscopy Experiment

Time-resolved experiments using femtosecond duration light pulses allow us to follow reactions as they happen. Our group uses a variety of techniques that provide windowless observations, allowing us to monitor chemical change from initial reactants through to final products. In this talk I will specifically focus on the use of high energy photons from a high harmonic generation source and how this allows us to monitor previously unseen aspects of photochemical reactions in a time-resolved photoelectron spectroscopy experiment. During the talk I will focus on two experiments, one where we have monitored traditional transition state driven dynamics, and a second experiment where we are able to monitor the dynamics of a roaming reaction: capturing both the formation and destruction of a roaming intermediate for the first time.
