Electron Paramagnetic Resonance: Elementary Theory and Practical Applications. Electron Spin Resonance Spectroscopy or It’s fun to flip electrons! These include organic free radicals,2 biradicals, 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. ���xFi��M����PJ�x�;4 �6�s�$yhR�� �FY�r>���Sx�r@J���X�@Iܼu��K�3x�Z~�Nj��I;_����3*��̳ǰ���&�RF��L`�C�骀|� National Biomedical ESR Center, The Medical College of Wisconsin, Milwaukee. ΃���B�y����g;�0^�K}T��F�2-~`�����Q���. 0000001577 00000 n endstream endobj 138 0 obj <> endobj 139 0 obj <> endobj 140 0 obj <>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/ExtGState<>>> endobj 141 0 obj <> endobj 142 0 obj <> endobj 143 0 obj <> endobj 144 0 obj [/ICCBased 152 0 R] endobj 145 0 obj <> endobj 146 0 obj <> endobj 147 0 obj <> endobj 148 0 obj <>stream The electron spin resonance spectrum of a free radical or coordination complex with one unpaired electron is the simplest of all forms of spectroscopy. 2.2.1 Introduction.

This will be achieved by looking for the “spin-flip” transition of a free (unpaired) electron exposed to a magnetic field. 0000002928 00000 n 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. The phenomenon of electron spin resonance (ESR) is based on the fact that an electron is a charged particle. See search results for this author.
