Electron-nuclear double resonance. [PDF]
Photosynth Res, 2009 The application of electron-nuclear double resonance (ENDOR) spectroscopy for the investigation of photosynthetic systems is reviewed. The basic principles of continuous wave and pulse ENDOR are presented. Selected examples of the application of the ENDOR technique for studying stable and transient paramagnetic species, including cofactor radical ions,

Increased sensitivity in electron–nuclear double resonance spectroscopy with chirped radiofrequency pulses [PDF]
Magnetic ResonanceElectron–nuclear double resonance (ENDOR) spectroscopy is an EPR technique to detect the nuclear frequency spectra of hyperfine coupled nuclei close to paramagnetic centers, which have interactions that are not resolved in continuous wave EPR spectra and

Reverse dynamic nuclear polarisation for indirect detection of nuclear spins close to unpaired electrons [PDF]
Magnetic Resonance, 2022 Polarisation transfer schemes and indirect detection are central to magnetic resonance. Using the trityl radical OX063 and a pulse electron paramagnetic resonance spectrometer operating in the Q-band (35 GHz, 1.2 T), we show here that it is possible to ...

A primer in pulse EPR-based hyperfine spectroscopy for NMR spectroscopists
Journal of Magnetic Resonance Open, 2023 The theoretical foundations of NMR and EPR are very similar. Nevertheless, the fields differ significantly in practical aspects. This primer is an attempt to bridge some of the gaps between the fields, and at the same time it highlights some applications

Electron-nuclear double resonance of interstitial chromium in silicon [PDF]
Physical Review B, 1987 The positively charged state of interstitial chromium in silicon was investigated using electron-nuclear double resonance. We have found the hyperfine interaction of the impurity electrons with nine shells of surrounding silicon neighbors containing 102 atoms.
