Davies Electron-Nuclear Double Resonance Revisited: Enhanced Sensitivity and Nuclear Spin Relaxation
Over the past 50 years, electron-nuclear double resonance (ENDOR) has become a fairly ubiquitous spectroscopic technique, allowing the study of spin transitions for nuclei which are coupled to electron spins.

Electron Nuclear Double Resonance
2003In the previous chapters the usefulness of EPR for the characterization of defect structures was demonstrated. EPR is usually a powerful tool, in particular, for preliminary first information about the main symmetry properties of the defect. If optical detection of magnetic resonance is applicable, additional knowledge about the nature of the defect ...

Electron Nuclear Double Resonance
Annual Review of Physical Chemistry, 1971Feher introduced the electron nuclear double resonance or ENDOR technique in 1 956 (1) . In the ensuing 1 5 years several hundred ENDOR related articles have been published. However, no general review of the subject has appeared. This may be partially due to the fact that ENDOR results Can be thought of as an extension of the usual paramagnetic ...

Electron-nuclear double resonance of 55Mn2+ in MgO
Physics Letters A, 1967Abstract ENDOR techniques were used to determine the cubic crystalline field splitting a, and the nuclear spin Hamiltonian parameters A, gIμN, and U of 55Mn2+ in MgO at 4.2°K. The nuclear magnetic moment of 55Mn has been dereived to be +(3.437 ± 0.005)μN.

Electron-nuclear double resonance (endor) of pitches
Carbon, 1984Abstract A preliminary study of Electron-Nuclear Double Resonance (ENDOR) has been carried out on carbonaceous pitches and their solutions. Large matrix and hyperfine ENDOR signals have been observed, the former being very sensitive to temperature, i.e. molecular motion.

Electron nuclear double resonance studies on polyacetylene
The Journal of Chemical Physics, 1984ENDOR measurements have been carried out on trans-polyacetylene and on 0.5 mol % ReF6 doped 70% cis-polyacetylene at 4 K. The pure trans-polyacetylene yields only a single line, but the ReF6 doped material yields two hyperfine couplings to hydrogens of 0.2 and 1.7 MHz. Calculations suggest the average chain length of the soliton is 93 carbon atoms. The

Electron nuclear double resonance.
1963The subject of this thesis is the work done in the Eaton Electronics Research Laboratory as a beginning of a programme of studies of double resonance. The aim of this work is to find out the conditions under which the best ENDOR signal can be obtained.

Field-Cycled Electron Nuclear Double Resonance
The Journal of Physical Chemistry, 1994An electron nuclear double resonance experiment is described which allows the detection of zero-field nuclear quadrupole resonance transitions by observing the unpaired electron spins under field cycling conditions. The feasibility of this kind of experiment is demonstrated by the detection at 2 K of pure deuteron quadrupole transitions in diamagnetic ...

Electron-nuclear double resonance of copper complexes of human transferrin
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1983Electron-nuclear double resonance (ENDOR) spectroscopy has been used to study ligand and copper hyperfine interactions in Cu(II) complexes of human transferrin. A nearly isotropic superhyperfine interaction of the Cu(II) spin with a single 14N nucleus was identified, and the principal values of its tensor were estimated.

Electron-Nuclear Double Resonance of Charcoals
1984ENDOR (Electron-Nuclear Double Resonance), which was proposed and demonstrated by G. Feher in 1956 (1) is a modification of ESR (Electron Spin Resonance) involving the interaction between nuclear and electron spins in paramagnetic materials. ENDOR belongs to the class of methods called “Double Resonance” in which one transition between atomic or ...
