Electron nuclear double resonance

Electron nuclear double resonance (ENDOR) is a magnetic resonance technique for elucidating the molecular and electronic structure of paramagnetic species. The technique was first introduced to resolve interactions in electron paramagnetic resonance (EPR) spectra. It is currently practiced in a variety of modalities, mainly in the areas of biophysics and heterogeneous catalysis.

The technique was first introduced to resolve interactions in electron paramagnetic resonance (EPR) spectra. It is currently practiced in a variety of modalities, mainly in the areas of biophysics and heterogeneous catalysis. In the standard continuous wave (cwENDOR) experiment, a sample is placed in a magnetic field and irradiated sequentially with a microwave followed by radio frequency. The changes are then detected by monitoring variations in the polarization of the saturated electron paramagnetic resonance (EPR) transition.
