Establishing XANES Signatures of Rhenium Oxidation States: A Combined Theoretical and Experimental Reference Study for Analytical Applications

Key Points

• The aim is to establish reference datasets of xanes signatures for rhenium oxidation states to support analytical applications.
• Conduct x-ray absorption near edge structure (xanes) spectroscopy experiments on rhenium samples.
• Combine theoretical and experimental approaches to generate reference datasets.
• Analyze the oxidation states and local coordination environment of the transition metals.
• The study successfully establishes xanes signatures for various rhenium oxidation states.
• Reference datasets provide a systematic understanding of rhenium in analytical contexts.
