Hadashot Arkheologiyot - Excavations and Surveys in Israel, 2023
In November 2017, a salvage excavation was conducted at H orbat Endor (Permit No. A-8146; map ref. 236108/727261; Fig. 1), prior to works on the Dovrat–Newe Ur gas line. The excavation, on behalf of the Israel Antiquities Authority and funded by Israel Natural Gas Lines Ltd., was directed by Y. Har’el (field photography), assisted by Y.

Review of Scientific Instruments, 1978
We report the design and construction of a high-quality ENDOR cavity from a naturally occurring rock, ’’Wonderstone.’’ It consists of a cylindrical cavity operated in the TE011 mode, with four vertical posts forming the ENDOR coil. 100 kHz field modulation is achieved by external coils mounted on the pole faces of the magnet.

Journal of Magnetic Resonance, 2005
A pulsed ENDOR spectrometer operating at a microwave frequency of 275 GHz is described. The results demonstrate that this type of spectroscopy can now be performed routinely at this high microwave frequency. The advantages compared to conventional EPR frequencies are the high spectral resolution, time resolution, and sensitivity.

Molecular Physics, 1969
The ENDOR spectra of Tschitschibabin's hydrocarbon and certain of its specifically deuterated derivatives have been measured. To interpret these spectra the factors determining the ENDOR spectrum of a biradical are discussed in detail. The analysis reveals that the paramagnetic species present in solutions of Tschitschibabin's hydrocarbon and ...

Abstract A new method is described to generate subsystem ESR spectra and hyperfine-selective ENDOR spectra. It is based on a pulsed ENDOR scheme that achieves hyperfine selectivity by a rapid magnetic field jump between the microwave pulses. The procedure allows the measurement of hyperfine and quadrupole couplings that are not resolved in a ...

This book offers an analysis of the way early modern English literature addressed the period's anxieties about witchcraft and theatricality. What determined whether or not a demonologist imagined a trial as a spectacle? What underlying epistemological constraints governed such choices and what conceptions of witchcraft did these choices reveal? Pairing

Metalloprotein — Endor- Spectroscopy
1995The theoretical foundations for the application of high-resolution electronnuclear-double-resonance spectroscopy to the determination of structural properties of the prosthetic group in randomly oriented metalloproteins are delineated. Applications described involve Superoxide Dismutase as a copper-containing protein and Enoate Reductase as an iron ...

ENDOR parameter measurements for free radicals in solution from CW-ENDOR
Journal of Magnetic Resonance (1969), 1983Abstract This analysis gives the computation of the ENDOR relaxation parameters ( Ω n , T n , Ω en ) from experimental data for a low-power CW-ENDOR spectrometer by applying Freed's theory. For resolved and Lorentzian EPR lines resulting from the interaction of the electronic spin with a single nuclear species, Ω n
