Progress in technology in recent decades has brought not only huge leaps in our knowledge across many fields, but has also led to the development of new tools that help and support the pursuit of such knowledge. Spectroscopy, the study of the interaction between matter and electromagnetic radiation, is used in chemistry, physics, astronomy and other fields, and allows scientists to investigate the physical and electronic structure as well as composition of materials. A number of techniques, including X-ray spectroscopy, have been developed to detect and measure materials in this way. Dr Tetsuo Katayama, from the Japan Synchrotron Radiation Research Institute (JASRI), is part of a team furthering research in this field.

Understanding the ultrafast dynamics of molecules is of fundamental importance. Time-resolved X-ray absorption spectroscopy (TR-XAS) is a powerful spectroscopic technique for unveiling the time-dependent structural and electronic information of molecules that has been widely applied in various fields. Herein, the design and technical achievement of a newly developed experimental apparatus for TR-XAS measurements in the tender X-ray range with X-ray free-electron lasers (XFELs) at the Pohang Accelerator Laboratory XFEL (PAL-XFEL) are described. Femtosecond TR-XAS measurements were conducted at the Ru L 3-edge of well known photosensitizer tris(bipyridine)ruthenium(II) chloride ([Ru(bpy)3]2+) in water. The results indicate ultrafast photoinduced electron transfer from the Ru center to the ligand, which demonstrates that the newly designed setup is applicable for monitoring ultrafast reactions in the femtosecond domain.
