Femtosecond-XES characterization of spin-states and structures of transient iron(III)-oxyl species

Compounds of iron with oxygen are relevant for many processes - from the transport of oxygen in the blood to the corrosion of iron. However, many aspects of iron-oxygen chemistry are not yet fully understood. It is generally believed that the magnetic orientations of the electrons involved - the so-called spin state - also play an important role, e.g. in catalytic processes. Using...

The MID instrument at the European XFEL

At the MID instrument of European XFEL, researchers can investigate the structure and dynamics of materials with molecular to atomic resolution. To do this, they focus X-ray pulses on the material to be studied from where the X-rays are scattered in different directions. The arrangement of the atoms in the material leads to a characteristic scattering pattern, which is recorded by a detector....
