Abstract:
Invited for the cover of this issue are Prof. Jochen Autschbach and Dr. Dumitru-Claudiu Sergentu of State University of New York at Buffalo, and Dr. Corwin H. Booth of Lawrence Berkeley National Laboratory. The image depicts high-energy X-ray beams as lightnings probing Ce at the L3 edge in the iconic covalent-bonded Ce(C8 H8 )2 and in CeO2 . The mountain peaks in the background represent the double-peaked L3 edges. The peaks turn out to be intuitively interpreted in terms of localized orbitals and hence metal oxidation states.
