Cross‐Polarization Electron‐Nuclear Double Resonance Spectroscopy [PDF]

ChemPhysChem, 2015
AbstractMagnetic nuclei in the proximity of a paramagnetic center can be polarized through electron‐nuclear cross‐polarization and detected in electron‐nuclear double resonance (ENDOR) spectroscopy. This principle is demonstrated in a single‐crystal model sample as well as on a protein, the β2 subunit of E.coli ribonucleotide reductase (RNR), which ...

Extending the range of distances accessible by 19F electron-nuclear double resonance in proteins using high-spin Gd(III) labels [PDF]

, 2023
Fluorine electron-nuclear double resonance (19F ENDOR) has recently emerged as a valuable tool in structural biology for distance determination between F atoms and a paramagnetic center, either intrinsic or conjugated to a biomolecule via spin labeling ...

Site-selective generation of lanthanoid binding sites on proteins using 4-fluoro-2,6-dicyanopyridine [PDF]

Magnetic Resonance, 2022
The paramagnetism of a lanthanoid tag site-specifically installed on a protein provides a rich source of structural information accessible by nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) spectroscopy.

Electron-nuclear-double-resonance studies of spinach plastocyanin [PDF]

Biochemical Journal, 1983
Electron-nuclear-double-resonance (ENDOR) studies of spinach plastocyanin revealed that 14N-hyperfine couplings from its two co-ordinated imidazole groups are characteristically small in anisotropy and relatively high in ENDOR frequencies and that the two imidazole groups are magnetically equivalent.

Coherent state transfer between an electron and nuclear spin in (15)N@C(60). [PDF]

, 2011
Electron spin qubits in molecular systems offer high reproducibility and the ability to self-assemble into larger architectures. However, interactions between neighboring qubits are "always on," and although the electron spin coherence times can be ...

Increased sensitivity in electron–nuclear double resonance spectroscopy with chirped radiofrequency pulses [PDF]

Magnetic Resonance
Electron–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

Electron-nuclear double resonance in melanins

Biophysical Journal, 1976
Electron-nuclear double resonance (ENDOR) signals from matrix protons interacting with the stable free radicals of "A"- and "B"-type melanins have been observed as a function of pH. In all samples the single line is similar in width and unusually narrow.
