Electron Paramagnetic Resonance

Electron Paramagnetic Resonance (EPR) is a technique used to study materials with unpaired electrons, such as certain metals and radicals. When these unpaired electrons are placed in a magnetic field, they can absorb specific radiofrequency radiation, causing their spins to flip. By measuring these absorption signals, scientists can gather detailed information about the electronic environment, structure, and dynamics of the material. EPR is especially valuable in chemistry, physics, and biology for studying molecules, metal complexes, and biological systems with unpaired electrons.
