Electron-Nuclear Double Resonance of Charcoals

1984
ENDOR (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 ...

Matrix Line in Pulsed Electron-Nuclear Double Resonance Spectra

Journal of Magnetic Resonance, 1998
The intense line in Mims and Davies electron-nuclear double resonance (ENDOR) spectra due to the hyperfine interactions of an unpaired electron with distant matrix nuclei is shown to originate from a simultaneous inversion of a large number of nuclear spins by a radiofrequency pulse.

Electron-nuclear double-resonance experiments in hydrogenated amorphous silicon

Physical Review B, 1986
Electron-nuclear double-resonance (ENDOR) measurements are performed in undoped, doped, and compensated a-Si:H. Matrix ENDOR and distant ENDOR are identified as the effective ENDOR mechanisms by an investigation of the transient ENDOR response, and conditions for the experimental parameters to optimize the response are given. ENDOR spectra due to $^{1}\

Electron-Nuclear Double Resonance and Relaxation in RbMnF3

Journal of Applied Physics, 1969
Electron-nuclear double resonance has been observed in RbMnF3 at liquid-helium temperatures. Nuclear saturation, which was induced by applying a large amplitude UHF signal to the sample, was detected as a shift in the field required for AFMR at x-band frequencies.

Electron nuclear double resonance of interstitial iron in silicon

Physical Review B, 1984
We report on the first electron nuclear double-resonance investigation of an interstitial deep-level defect in silicon. For interstitial iron the superhyperfine interactions with six shells of neighbor nuclei comprising 42 silicon atoms could be resolved and determined.

Hyperfine-correlated electron nuclear double resonance spectroscopy

Chemical Physics Letters, 1995
Abstract A pulse electron nuclear double resonance method is proposed that correlates the hyperfine splittings to the nuclear transition frequencies in a two-dimensional experiment. Since the technique makes use of selective radio frequency excitation in a time-domain experiment it can be applied to ordered systems as well as to disordered systems ...

Electron-Nuclear Double Resonance Studies of Color Centers

Physical Review, 1962
The electron-nuclear double resonance (ENDOR) method is applied to the study of the interaction of F-center elections with the first two nuclear shells in NaCl, KBr, and NaH. From the angular dependence of single-crystal ENDOR spectra, values are obtained for the isotropic magnetic interaction constants and the principal values of the magnetic and ...

Electron Paramagnetic Resonance and Electron Nuclear Double Resonance Spectroscopy

1990
An unpaired electron can be aligned by an applied magnetic field so that its spin is precessing about the field. The direction of spin precession can be either clock- or anticlockwise corresponding to the two energy states of the electron (Fig. 1). Irradiation with an electromagnetic beam of the correct frequency can induce transitions of the unpaired ...

Electron nuclear double resonance of trivalent gadolinium in thoria

British Journal of Applied Physics, 1965
Electron nuclear double resonance measurements on gadolinium 157 substituted into crystals of thoria have provided the following values for the hyperfine interaction parameters: A = 15.806 ± 0.013 Mc/s, B = -0.687 ± 0.018 Mc/s and the nuclear magnetic moment μN = - 0.337 ± 0.003 nuclear magnetons.
