135 Ba and 137 Ba Fourier transform NMR and NQR studies
TLDR
In this paper, the ratios of g1-factors, hyperfine structure anomalies, magnetic moments, atomic shielding constants and the ratio of the quadrupole moments are evaluated using also data from literature.Abstract:
135Ba and137Ba Fourier transform nuclear magnetic resonance and nuclear quadrupole resonance investigations are reported in liquids resp. solids. From these measurements ratios of g1-factors, hyperfine structure anomalies, magnetic moments, atomic shielding constants and the ratio of the quadrupole moments are evaluated using also data from literature.read more

TL;DR: The chemical shift, delta, is redefined to avoid previous ambiguities but to leave practical usage unchanged, and Relations between the unified scale and recently published recommendations for referencing in aqueous solutions are discussed, as well as the special effects of working in the solid state with magic-angle spinning.

TL;DR: In this article, a unified scale for reporting the NMR chemical shifts of all nuclei relative to the 1H resonance of tetramethylsilane is proposed, which is designed to provide a precise ratio, Ξ, of the resonance frequency of a given nuclide to that of the primary reference.

Nuclear magnetic relaxation
TL;DR: The method of nuclear paramagnetic resonance absorption has been used to study the interaction of nuclei in solids, liquids, and gases with their environment and one can predict the relaxation time T1 caused by interaction of the nuclei with the lattice vibrations.
