X-band ENDOR and S-band ESEEM of paramagnetic disordered solids
X-band ENDOR and S-band ESEEM have been employed in this study to measure weak electron-nuclear hyperfine and nuclear electric quadrupole couplings in paramagnetic disordered solids. In the X-band ENDOR investigation, radicals generated from perylene adsorbed on catalytically active alumina and …

Anisotropic EPR and ENDOR studies of sulfur-containing heterocyclic compounds adsorbed on silica-alumina surfaces
The physical phenomenon of an organic molecule adsorbing onto a silica-alumina surface is a topic of great interest. Many questions concerning exactly how this phenomenon occurs still remain unanswered. Although Electron Paramagnetic Resonance and Electron-Nuclear Double Resonance techniques are …

A magnetic resonance study of iron in silver chloride
… 1.3°K by the Electron Nuclear Double Resonance (ENDOR) technique. ENDOR lines from 6 to 24 megacycles were observed on each of the five electron spin resonance transitions and have been identified as lines due to four chlorine nuclei which are nearest neighbors to the iron ion. The angular …

Divination in 1 Samuel 28 and Beyond: An African Study in the Politics of Translation
… in 1 Samuel 28:3-27--the oft-called "Witch of Endor" passage. My thesis is that much of the vocabulary of divination in this passage and beyond has been mistranslated in authorized English and other translations used in Africa and in scholarly writings. I argue that the woman of Endor is not a …

Computer-assisted analysis of electron magnetic resonance spectra and the electron nuclear double resonance spectrum of isolated perylene cations
… such as electron nuclear double resonance (ENDOR) spectroscopy, requires simulation of the experimental spectra. Simulating an experimental spectrum involves varying the values of several spectral parameters until the resultant simulation best reproduces the experimental spectrum. …

The Free Radical Nature of Compound I From Horseradish Peroxidase and Chloroperoxidase
… Mossbauer and electron nuclear double resonance (ENDOR) spectra. These spectral techniques were used to prove that one of the two oxidation equivalents associated with Compound I consists of a porphyrin centered pi-cation radical.

Part~I: Determination of Quadrupole Couplings via L-Band, B(0) // B(1) EPR. Part~II: Surface Interactions of Perylene Adsorbed on Oxide Powders
… (matrix) of the radicals were also probed by ENDOR spectroscopy. Depending on the nature of the sample and experimental conditions, signals could be detected from $\sp1$H, $\sp2$D, and $\sp{27}$Al. The source and behavior of these signals are investigated with special attention paid to …

Dioxygen activation and substrate hydroxylation by the hydroxylase component of toluene/O-xylene monooxygenase from pseudomonas sporium OX1
… by rapid-freeze quench (RFQ) EPR, Mossbauer, and ENDOR spectroscopy and stoppedflow optical spectroscopy. For the I100W mutant, a transient species is observed with an absorption maximum at 500 nm. EPR and Mossbauer spectra of RFQ samples identified this species as a diiron(III,IV) cluster …

Electron Spin Echo and Millimeter Wave Epr Studies of Disordered Solids
… electron nuclear double resonance (ENDOR) and continuous wave electron paramagnetic resonance (cw EPR) techniques are better suited to study strong short range ($$35 GHz) experiments should result in enhanced resolution or allow for more accurate determinations of the zero-field …

Characterizations on bacterial photosynthesis and respiration with optical spectroscopy and magnetic resonance
… the semiquinone signal, with which the Davies ENDOR are carried out at Q-band (35 GHz). The higher frequency allows selective excitation of different orientations of semiquinone with respect to the external magnetic field. Our simulations on the ENDOR spectra reveal the Euler angles needed to …
