Electron Paramagnetic Resonance (EPR), also known as Electron Spin Resonance (ESR) , is a spectroscopic technique used to study materials containing unpaired electrons. In polymer science, ESR/EPR is valuable for investigating various aspects, including polymer structure, dynamics, degradation, and the behavior of free radicals.
EPR focuses on materials with unpaired electrons. Polymers, by their nature, are often diamagnetic (all electrons are paired). However, unpaired electrons can be introduced or generated in polymers through various processes, making them amenable to EPR study.
