Electron Paramagnetic Resonance (EPR) Spectroscopy Technology

Electron paramagnetic resonance (EPR) spectroscopy technology is a spectral detection method that uses unpaired electrons to analyze the chemical structure information of paramagnetic materials. EPR technology originated from the study of physics, initially used to study the electronic structure of some complex atoms, molecular structure, crystal structure and other problems, and later extended to the biochemical field of organic compounds analysis and characterization. In the fields of electrochemistry, REDOX chemistry, photochemistry and catalysis, EPR can be used to study metal centers and free radicals involved in chemical processes. In many areas of materials science, EPR is used in polymer synthesis, testing the purity of silicon in solar cells, characterization and grading of nanodiamonds.
