abstract = "Following the coupled motion of electrons and nuclei in molecules is dificult if one uses time-resolved approaches that only provide direct information on one or the other. We combine two complementary measurements, Time-Resolved Photoelectron/PhotoIon Spectroscopy (TRPES and TRPIS) and Ultrafast Electron Diffraction, to follow the electronic and nuclear dynamics of gas phase CH2I2 when exposed to UV light. In order to interpret the measurement, trajectory surface hopping calculations are carried out and all the measurement observables are simulated and directly compared with the measurement signals. Our measurements highlight the coupled electron-nucleus dynamics that allow for electronic potential energy to be converted into nuclear kinetic energy as well as complicated structural rearrangements of the molecule that involve symmetry breaking, dissociation, rotation, and non-local wave-packet dynamics.",
