Signatures of technetium oxidation states: a new approach [PDF]

Chem. Commun., 2020, 56, 9608-9611, 2020
A general strategy for the determination of Tc oxidation state by new approach involving X-ray absorption near edge spectroscopy (XANES) at the Tc L3 edge is shown. A comprehensive series of 99Tc compounds, ranging from oxidation states I to VII, was measured and subsequently simulated within the framework of crystal-field multiplet theory.
