What Types of NMR Techniques Are Used in Catalysis?
Several specialized NMR techniques are commonly used in catalysis research:
1. Solid-State NMR: Ideal for studying solid catalysts, solid-state NMR can provide information about the structure and dynamics of heterogeneous catalysts. 2. In Situ NMR: This technique allows the observation of catalysts and reactions under actual operating conditions, providing real-time insights into catalytic processes. 3. Magic Angle Spinning (MAS) NMR: MAS NMR enhances the resolution of solid-state NMR by averaging out anisotropic interactions, making it particularly useful for studying complex catalyst materials. 4. 2D NMR Spectroscopy: Two-dimensional NMR techniques, such as COSY and NOESY, provide detailed information about the spatial relationships between nuclei, aiding in the structural elucidation of catalyst molecules.
