Summary, in English

Resonant photoelectron spectroscopy (RPES) has been used to probe electronic structure properties of the closed-shell [FeII(CN)6]4− and open-shell [FeIII(CN)6]3− prototype transition metal complexes in aqueous solution. Site-selective Fe 2p (L-edge) RPES mapsprovide new insight into spin-coupling processes at the core-excited metal centers, with autoionization of [FeIII(CN)6]3− showing a dramatic (∼4×)
singlet versus triplet final-state enhancement. This shows that RPES
provides unique opportunities to study spin-dependent electronic
properties in transition metal based functional materials.
