Overlapping absorption edges will occur when an element is present in multiple oxidation states within a material. DetOx is a program for partitioning overlapping X-ray absorption spectra into contributions from individual atomic species and computing the dependence of the anomalous scattering factors on X-ray energy. It is demonstrated how these results can be used in combination with X-ray diffraction data to determine the oxidation state of ions at specific sites in a mixed-valance material, GaCl2 .

Congratulations to Karim Sutton, who has been awarded a Margaret C. Etter Student Lecturer Award at the recent American Crystallographic Association annual meeting in Boston.

He presented his recent research determining oxidation states in mixed-valent materials using tunable synchrotron radiation on Diamond beamline I19.

The awards were established to honour the memory of Professor Etter (1943-1992), who was a major contributor to the field of organic solid-state chemistry.
