Abstrakt:	L3‐edge high‐energy‐resolution fluorescence‐detection X‐ray absorption near‐edge structure (XANES) spectra for palladium and rhodium compounds are presented, with focus on their electronic structures. The data are compared with transmission XANES spectra recorded at the K‐edge. A correlation between the absorption edge energy and the metal ion oxidation state is not observed. Despite the different filling of the 4d orbitals and different local coordination, the Rh and Pd compounds show remarkably similar spectral shapes. Calculation of the density of states and of the L3‐XANES data reproduce the experimental results. [ABSTRACT FROM AUTHOR]
