How are Electronic Transitions Studied in Catalysis?
Various spectroscopic techniques are employed to study electronic transitions in catalysis. Some of the most common methods include:
- UV-Visible Spectroscopy: This technique measures the absorption of light in the ultraviolet and visible regions, providing insights into electronic transitions involving valence electrons. - X-ray Absorption Spectroscopy (XAS): This method is used to probe the electronic structure of catalysts, particularly the oxidation states and coordination environment of metal centers. - Electron Paramagnetic Resonance (EPR) Spectroscopy: EPR is used to study unpaired electrons in catalysts, which can provide information about electronic transitions involving radicals or metal centers with odd-electron configurations.
