Abstract
We have performed the first time-resolved X-ray absorption spectroscopy using the SPring-8 Angstrom Compact Free Electron laser (SACLA) with a dual X-ray beam dispersive detection method. The test compound is aqueous 0.5 M ammonium iron(III) oxalate trihydrate solution. The photoexcited iron complex exhibits a red shifted iron K-edge with a rise time constant of 260 fs. The X-ray absorption difference spectra between the presence and absence of pump pulses are independent of time delay between 1.5 and 100 ps, indicating that the photoexcited species is long-lived.
