Electron Spin Resonance (ESR) of Organic Free Radicals: selected examples from the literature

摘要

INTRODUCTION Electron spin resonance (ESR), which is also called electron paramagnetic resonance (EPR), is a spectroscopic technique responsive to transitions involving unpaired electrons and therefore can be used for studying organic free radicals containing one or more unpaired electrons. This lesson is completely dedicated to the application of ESR spectroscopy to -the study of free radicals species encountered in organic chemistry.
