Core Level X-ray Spectroscopy

Core-level X-ray spectroscopy as element specific probe which can be employed to study the electronic structure at variable temperature and pressure and with time resolution down to the femtosecond time scale. Changes in spin states and chemical bonding can be followed during ultra-fast chemical dynamics.
In experiments, the dynamics is typically synchronously initiated with IR, optical or UV pump pulses. The insight gained by these techniques can have strong impact on technological applications and on the basic understanding of chemical bonding and light-matter interactions. The analysis of the core-level spectra in combination with theoretical calculations discloses detailed electronic and structural information, such as charge transfer, nature of bonding, hybridization, chemical environment, site symmetry.
