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.

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

Comparison of ESEEM, ESE-ENDOR, and CW-ENDOR on 14N in a powder
Journal of Magnetic Resonance (1969), 1986Abstract Three different techniques were applied for the determination of the 14 N couplings in powdered 0.3% copper-doped nickel(II)bis( NN -diethyl dithiocarbamate): electron spinecho envelope modulation (ESEEM), electron spin-echo ENDOR, and continuous-wave ENDOR.

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

Physica B+C, 1976
Abstract The parameters of the nuclear terms in the spin Hamiltonian have been determined with ENDOR for 155Gd3+ and 157Gd3+ in LaCl3, using the natural distribution of isotopes. The quadrupole coupling data, investigated on the basis of the model of Newman and Price, indicate considerable local distortion around Gd3+.

The 14N ENDOR of the radical anion (SO3)2NO= has been observed in fluid solutions in water and in water-ethanol mixtures, and trapped in irradiated single crystals of potassium hydroxylamine disulphonate. The quadrupole coupling has been estimated from the solid-state spectra and it is argued that this interaction is too weak to provide a significant ...

An ENDOR spectrometer has been developed which is especially suitable for studying ligand hyperfine interactions. The complicated ligand ENDOR spectra are considerably simplified by alignment of the crystalline axes relative to the magnetic field direction.

Fuel, 1990
Abstract Coals with carbon contents of 76 and 82 wt%, respectively, and their mixtures with ethylenediamine, were investigated by 1 H ENDOR spectroscopy. In all cases the spectra obtained had a single line centred on the free proton frequency and one or two pairs of lines indicating a weak electron-nuclear interaction.
