What Techniques are Used to Measure Chemical Shifts in Catalysis?
Several techniques are employed to measure chemical shifts in the context of catalysis, including: - Nuclear Magnetic Resonance (NMR) Spectroscopy: The most commonly used technique for measuring chemical shifts, providing detailed information about the electronic environment of nuclei. - Electron Paramagnetic Resonance (EPR) Spectroscopy: Used for systems with unpaired electrons, such as transition metal complexes, to study changes in the electronic environment. - X-ray Absorption Spectroscopy (XAS): Can provide information about the electronic structure of metal centers in catalysts through shifts in absorption edges.
