TL;DR: In this article, the resonance of Cl 35 in α phase p -dichlorobenzene containing various impurities was studied and the characteristic number which represents the number of resonant nuclei which are affected by an impurity molecule was measured.
Abstract: The resonance of Cl 35 in α phase p -dichlorobenzene containing various impurities was studied. The used impurities were p -BrφCl, p -Br 2 φ, p -I 2 φ, p -OHφCl, p -CH 3 φCl, p -NH 2 φCl, p -NO 2 φCl, p -NO 2 φCH 3 and p -(CH 3 ) 2 φ. The characteristic number which represents the number of resonant nuclei which is affected by an impurity molecule was measured. This characteristic number depends on the volume difference of the resonant and impurity molecules and independent on the difference in dipole moment. The results of the theoretical discussions supported the experiment. The height, width, shape and the integrated intensity of the resonance line were also measured. The integrated intensity was almost constant in the range of small concentration of impurity and then decreased.

TL;DR: The roles of ultrahigh magnetic fields, radiofrequency pulse sequences, dynamicnuclear polarization, dynamic nuclear polarization, isotopic enrichment, and nuclear quadrupole resonance in opening up the periodic table to in-depth study are discussed.
Abstract: Selected highlights of the recent literature on solid-state NMR of some of the lesser studied nuclei are provided. The roles of ultrahigh magnetic fields, radiofrequency pulse sequences, dynamic nuclear polarization, isotopic enrichment, and nuclear quadrupole resonance in opening up the periodic table to in-depth study are discussed.

TL;DR: In this article, the librational motions of the water molecules in polycrystalline barium chlorate monohydrate have been studied by using proton and deuterium zero-field NMR.
Abstract: The librational motions of the water molecules in polycrystalline barium chlorate monohydrate have been studied by using proton and deuterium zero-field NMR. In contrast to high-field NMR, subtle molecular motions produce readily observable changes in the zero-field spectrum. Computer simulations and application of a novel-pulsed zero-field technique confirm that the splitting observed in the zero-field spectrum of the hydrate results from the motionally induced asymmetry of the magnetic dipole-dipole coupling tensor.
