Description
I will present how we study chemical interactions and their ultrafast dynamics in transition-metal complexes and metalloproteins with soft x-ray spectroscopy. We use time-resolved and steady-state soft x-ray spectroscopy at synchrotron radiation sources, at x-ray free-electron lasers and in the laboratory. The importance of applying short x-ray pulses to the systems under investigation will be highlighted. I will discuss how we extract information on chemical properties based on the experimental observables, emphasize the importance of effective and efficient theoretical approaches and highlight the importance of choosing suitable sample preparation techniques and experimental procedures in general for avoiding x-ray beam damage of the samples.
