Abstract. Electron spin resonance ESR or electron paramagnetic resonance EPR spectroscopy is an experimental technique for detecting and characterizing chemical systems bearing one or more unpaired electrons. The application of the technique, the background of which is similar to the more diffused nuclear magnetic resonance NMR. For example, for the field of 3350 G shown at the right, spin resonance occurs near 9388.2 MHz for an electron compared to only about 14.3 MHz for 1 H nuclei. For NMR spectroscopy, the corresponding resonance equation is hv g N N B 0, where g N and N depend on the nucleus under study. Maxwell-Boltzmann Distribution. Electron spin resonance ESR spectroscopy is a direct and reliable method to identify and quantify free radicals in both chemical and biological environments. In this review, we discuss the use of ESR spectroscopy to study ROS generation mediated by nanomaterials, which have various applications in biological, chemical, and materials science.
