Non-adiabatic Excited State Molecular Dynamics

Following the coupled dynamics of electrons and nuclei in molecules on femtosecond timescales is key to under-standing many fundamental processes in physics, chemistry and biology. I will discuss a combination of experiments that probe such coupled (non-adiabatic) dynamics with a variety of approaches, including pulse shape spectroscopy, time resolved photoelectron spectroscopy and ultrafast electron diffraction. The measurements are compared with high level calculations of the measurement observables, allowing for detailed insight into the non-adiabatic dynamics.
