S2E6. EPR spectroscopy

In this episode of The Chemistry Show, we explore Electron Paramagnetic Resonance (EPR), also known as ESR, as a powerful spectroscopic technique for studying paramagnetic species. Unlike NMR, which probes nuclear spins, EPR focuses on unpaired electrons, making it indispensable for investigating radicals, transition-metal complexes, and catalytic intermediates. The episode begins with the fundamental principles and moves into transition-metal chemistry. Ultimately, this episode provides a structured guide to interpreting EPR spectra and demonstrates how magnetic and structural properties are deeply intertwined in paramagnetic systems.
