Electron paramagnetic spin resonance ligand

Electron paramagnetic resonance (EPR) spectroscopy. This is also known as electron spin resonance (ESR) spectroscopy and is the electron analogue of NMR. In the case of EPR, however, the magnetic moment is derived from unpaired electrons in free radical species and transition metal ions. The paramagnetism of many transition metal oxidation states has already been mentioned as a drawback to the observation of their NMR spectra, but it is the raison d etre behind EPR the technique is thus limited, in the case of metals, to those which are paramagnetic or which have free radicals as ligands. [Pg.48]
