The fast and non-adiabatic nature of photoinduced isomerization reactions makes it difficult to pin down their mechanisms. Time-resolved photoelectron spectroscopy using high energy photons and simulations can elucidate the mechanism of the ultrafast ring opening of thiophenone molecules in the gas phase.
