Spectroscopic Signature of Oxidized Oxygen States in Peroxides
Spectroscopic Signature of Oxidized Oxygen States in Peroxides
Recent debates on the oxygen redox behaviors in battery electrodes have triggered a pressing demand for the reliable detection and understanding of non-divalent oxygen states beyond conventional absorption spectroscopy. Here, enabled by high-efficiency mapping of resonant inelastic X-ray scattering (mRIXS) coupled with first-principles calculations, we report distinct mRIXS features of …
