Electron spin resonance (ESR) spectroscopy, also referred to as electron paramagnetic resonance (EPR) spectroscopy, is a versatile, nondestructive analytical technique which can be used for a variety of applications including: oxidation and reduction processes, biradicals and triplet state molecules, reaction kinetics, as well as numerous additional applications in biology, medicine and … Electron spin resonance spectroscopy (ESR) or electron paramagnetic resonance (EPR) is a technique for studying chemical species that have one or more unpaired electrons, such as organic and inorganic free radicals or inorganic complexes possessing a transition metal ion. Principles and Applications of ESR Spectroscopy fills the gap between the detailed monographs in ESR spectroscopy and the general textbooks in molecular physics, physical chemistry, biochemistry or spectroscopy. For further details on the theory and practice of ESR spectroscopy, refer to one of the excellent texts on ESR spectroscopy [2-9]. These include organic free radicals,2 biradicals, Pages 1-20. Basic Principles of Electron Spin Resonance. The basic interpretation of ESR spectra requires understanding of quantum mechanics and the use of matrix, vector, and tensor calculations. Basic EPR Theory 1.1 Introduction This course manual will provide the reader with a basic understanding needed to be able to get useful information using the technique of electron paramagnetic resonance (EPR) spectroscopy. ESR-1 Experiment #2B: Electron Spin Resonance Spectroscopy I. In ESR spectroscopy, molecules in a state containing unpaired electrons, .i.e., with non- ... the underlying principles of both these spectroscopic techniques are fairly simple. Electron Spin Resonance Spectroscopy Electron Spin Resonance (ESR) spectroscopy, also referred to as Electron Paramagnetic Resonance (EPR) spectroscopy, is a versatile, nondestructive analytical technique based on the absorption of microwave radiation in presence of an applied field by paramagnetic species.
