Introduction Electron spin resonance (ESR) spectroscopy has been used for over 50 years to study a variety of paramagnetic species. It targets materials containing unpaired electrons and possesses many applications. When Jewgeni Sawoiski first observed in 1944 electron spin resonance absorption in a copper(II) chloride dihydrate sample submerged in a 4.76 mT field at 133 MHz, electron paramagnetism had already been known for a long time. Ideal for researchers and students alike, the book provides a single source of NMR and EPR applications using a dynamic, holistic and multi-disciplinary approach. Instead of using complex mathematical derivations, the authors present a readily understandable approach to the field by interpreting sample spectra and classifying experimental data. Thanks to its comprehensive coverage, ranging from fundamental theory right up to the treatment of all important classes of organic radicals and triplet-state molecules that can be analyzed using ESR spectroscopy, this unique book is suitable for users in both research and industry. 5 0 obj This book provides an introduction to the underlying theory, fundamentals, and applications of EPR spectroscopy, as well as new developments in the area. Written by Fabian Gerson and Walter Huber, top experts in the field of electron spin resonance spectroscopy, this book offers a compact yet readily comprehensible introduction to the modern world of ESR.

Electron spin resonance (ESR) spectroscopy of Victorian brown coals reveal the presence of free radicals (Dack 1983, Dack et al., 1983). Other versions of this article Cecil Dybowski. We report a microresonator platform that allows room temperature detection of electron spins in volumes on the order of 100 pl, and demonstrate its utility to study low levels of dopants in perovskite oxides. Data are reported for mixtures of these melanins and for dopa-cysteinyldopa copolymers, which are spectroscopically similar. Download as PDF.
