Experiment 7 Electron Spin Resonance (ESR)

Using ESR (Electron Spin Resonance, also known as Electron Paramagnetic Resonance) you will be measuring one of the best known quantities in all of physics, the famous g s-factor of the electron. This will be achieved by looking for the “spin-flip” transition of a free (unpaired) electron exposed to a magnetic field. 7.1.1 ESR in Theory

ELECTRON SPIN RESONANCE (ESR) SPECTROSCOPY

Electron spin resonance (ESR), also called electron paramagnetic resonance (EPR), is a spectroscopic technique confined to the study of species having one or more unpaired electrons. Among the large number of systems having one or more unpaired electrons, i.e. paramagnetic system, the most important ones are free radicals, transition metal ions ...
