Paper Abstract

We report on the first measurements of a XANES spectrum of solvated Fe(CO)5 using an ultrafast laser driven plasma x-ray source operating at 2 kilohertz repetition rate. The measured spectrum is compared to theoretical XANES spectra based on DFT structure calculations of the solvated complex. The used x-radiation is generated by irradiating a solid metal target with ultrafast high-intensity laser pulses. The subsequently generated high-density plasma emits x-ray pulses with sub-picosecond temporal resolution and an x-ray spectrum extends to energies far higher than the desired spectral range. Since these spectral components potentially falsify the XANES measurements, they were suppressed by the x-ray optical setup.
