Beschreibung:
  • Optical excited molecules play an increasingly important role in research at light sources. Here we compare two approaches to structurally characterize such states, pumped-XAS and an innovative combination of EXAFS spectroscopy and resonant Raman scattering. The later combination allows to study efficiently charge-transfer complexes in their ground and excited state. The design of the experimental setups for pumped-XAS and resonant Raman scattering at different temperatures as well as results obtained are presented. We receive twofold information on the structural and electronic properties of both states elucidating the alterations upon induced charge transfer in the Cu 2O2-core of a system mimicking the active site of tyrosinase and hemocyanin. © 2009 IOP Publishing Ltd.
