Though less used than Nuclear Magnetic Resonance (NMR), Electron Paramagnetic Resonance (EPR) is a remarkably useful form of spectroscopy used to study molecules or atoms with an unpaired electron.It is less widely used than NMR because stable molecules often do not have unpaired electrons. 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. The degeneracy of the electron spin states characterized by the Electron spin resonance - 1 - CERN Teachers Lab Quick reference guide Introduction This is a model experiment for electron spin resonance, for clear demonstration of interaction between the magnetic moment of the electron spin with a superimposed direct or alternating magnetic field. 0000000016 00000 n

Selecting this option will search the current publication in context. The electron spin resonance spectrum of a free radical or coordination complex with one unpaired electron is the simplest of all forms of spectroscopy. 2 CHAPTER 4. JOHN A. WEIL is Professor Emeritus of Chemistry and Physics at the University of Saskatchewan and an active international researcher in the field of EPR and NMR spectroscopy and theory.. JAMES R. BOLTON is President of Bolton Photosciences, which provides specialty consulting services for the development and operation of ultraviolet (UV) technologies.
Electron Paramagnetic Resonance (EPR), also called Electron Spin Resonance (ESR), is a branch of magnetic resonance spectroscopy which utilizes microwave radiation to probe species with unpaired electrons, such as radicals, radical cations, and triplets in the presence of an externally applied static magnetic field. ESR is a purely quantum mechanical effect. EPR spectroscopy is similar to any other technique that depends on the absorption of electromagnetic radiation.

Electron paramagnetic resonance (EPR), also called electron-spin resonance (ESR), selective absorption of weak radio-frequency electromagnetic radiation (in the microwave region) by unpaired electrons in the atomic structure of certain materials that simultaneously are subjected to a constant, strong magnetic field.The unpaired electrons, because of their spin, behave like tiny magnets.

Electron spin resonance dating was first introduced to the science community in 1975, when Motoji Ikeya dated a speleothem in Akiyoshi Cave, Japan. It spins around its axis and this causes it to act like a tiny bar magnet. For further details on the theory and practice of ESR spectroscopy, refer to one of the excellent texts on ESR spectroscopy [2-9].

Introduction Electron spin resonance (ESR)1 has developed over the past several decades as a technique to provide information on the electronic structure of organic, inorganic, biological, solid state, and surface molecular species. Spin detection in volume-limited samples has applications in fields ranging from solid-state physics to structural biology (1–4).Magnetic resonance spectroscopies based on inductive detection are powerful and versatile techniques that can provide atomic-level structural and functional information for a wide range of samples under broadly variable conditions.
