Electron-Nuclear Double Resonance (ENDOR)

Electron Nuclear Double Resonance is a technique of measuring the hyperfine and quadrupole splitting of nuclear spins that are coupled to the electron spins.

Electron Nuclear Double Resonance is a technique of measuring the hyperfine and quadrupole splitting of nuclear spins that are coupled to the electron spins. Only those nuclei are measured that are coupled to the electron spins, and because it is measured via the EPR signal it is more sensitive than NMR . It can also be selective on site and orientation, by selecting positions within the EPR spectrum, for which the high g-value resolution at high fields is very helpful. A variety of ENDOR techniques, both pulsed and cw, are available, including triple-ENDOR.
