Soft X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS) have been performed on several nickel-containing bioinorganic complexes. RIXS spectral features are shown to be informative and diagnostic for the different oxidation states (Ni-II vs Ni-III) and spin states (high spin Ni-II vs low spin Ni-II) in these bioinorganic systems. In addition to the experimental results, multiplet simulation has also been performed to assist in understanding the observed XAS and RIXS features. These results demonstrate the power and complementarity of RIXS in identifying the electronic states for covalent and biorelevant complexes for the first time and pave the way for potential RIXS application to real biological systems.
