Description
Combining short pulse durations with high energy photons provides a unique experimental opportunity to explore fully photoinduced processes in molecular systems. High temporal resolutions allow us to explore ultrafast relaxation and interactions between high-lying electronic states. For photoionisation studies, being able to ionise molecules along the full reaction coordinate, even following relaxation to the ground state means we can capture the complete picture of a photochemical reaction. Alternatively, even higher energy photons can be used to provide a more localised picture of the chemical dynamics through core and inner valence ionisation processes. I will give several examples of such studies, looking at molecules such as pyrazine and a substituted ethylene, to illustrate the opportunities for high harmonic generation (HHG) in photochemical studies.
