Proton Nuclear Magnetic Resonance Spectroscopy
... Now, this would all be rather uninteresting if all the Hydrogen atoms in a molecule had nuclei that absorbed at exactly the same frequency; we would observe a single absorbance peak in the spectrum. However, locally, within a molecule, each Hydrogen atom will be in a different magnetic environment. ...

Electron paramagnetic resonance
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying materials with unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.
