Ultrafast photoelectron imaging spectroscopy enables observation of three-dimensional k-vector
distribution upon photoionization from non-stationary rovibronic states of a photoexcited molecule. The
time-energy mapping of photoelectron angular distribution uncovers ultrafast non-adiabatic electronic
transitions through conical intersections that are ubiquitous in polyatomic molecules. I discuss
photoelectron imaging apparatus and the deep UV and vacuum UV light sources that are used for this
methodology.
