Abstract: Solid-state nuclear magnetic resonance spectroscopy is highly sensitive for probing non-covalent interactions in solids that are of key interest for catalysis in chemical reactions and biological events. Fast magic-angle spinning at frequencies exceeding 100 kHz for instance enables the detection of proton nuclear spins engaged in hydrogen bonds or π-π interactions. Herein, applications to a host-guest complex based on cation-π interactions, enzymatic ATP hydrolysis, and immobilized supported ionic liquid phase-based catalysts are reviewed. We show how solid-state NMR combined with quantum-chemical calculations reveal atomic-level structural and dynamic insights into the importance of weak chemical interactions in catalysis.
