Electron Paramagnetic Resonance spectroscopy Electron Spin Resonance spectroscopy Principles of EMR spectroscopy B 0 D E h n Classical theory: Electron spin moment interacts with applied electromagnetic radiation Quantum theory: transitions between energy levels induced by. Like a proton, an electron has a spin, which gives it a magnetic property known as a magnetic moment. When an external magnetic field is supplied, the paramagnetic electrons can either orient in a direction parallel or antiparallel to the direction of the magnetic field.

Electron spin resonance has been used as an investigative tool for the study of radicals formed in solid materials, since the radicals typically produce an unpaired spin on the molecule from which an electron is removed. Particularly fruitful has been the study of the ESR spectra of radicals produced as radiation damage from ionizing radiation. Electron spin resonance (ESR) spectroscopy is able to directly measure the chemical species with unpaired electrons and has been widely used in a number of research fields. This review focused on its application in nutraceutical and food research.
