Lithium-Bridged Bis(silyl anion) of 9,10-Dimethyl-9,10-disilaanthracene.
Chemistry Letters, 1997Co-Authors: Ken Hatano, Kenji Morihashi, Osamu Kikuchi, Wataru AndoAbstract:In a low temperature 29Si NMR Spectrum measurement of 9,10-dimethyl-9,10-disilaanthracene dilithium (1), 29Si-7Li scalar coupling was observed. The 7Li NMR Spectrum showed the two different environments for these two lithium atoms in 1 at 168 K. The spectral analysis strongly suggests a structure which has singly bridged lithium for two silicon atoms (1d).

NMR STUDIES ON FAST IONIC CONDUCTOR LISICON CRYSTALS
2005Co-Authors: Li Zi-rong, Xue Rongjian, Chen LiquanAbstract:The temperature dependence of the linewidth of the 7Li NMR Spectrum line of LISICON crystals with different compositions and orientations has been investigated from 124 to 480k. It was found that there are three transition points of Li+ ion motion at ～273 K, ～350 K (for polycrystal ～320 K) and ～400 K respectively. The special behaviour of the electric quadrupole effects has been observed and discussed.

7Li NMR study of the ordering phenomena in the intrinsic two-component magnetoelectric material Li2ZrCuO4
Physical Review B, 2013Co-Authors: A. S. Moskvin, E. Vavilova, Stefan-ludwig Drechsler, Vladislav Kataev, B. BüchnerAbstract:We report an experimental and theoretical study of the low temperature 7Li nuclear magnetic resonance (NMR) spectra of oriented powder samples of γ-Li2ZrCuO4 (≡Li2CuZrO4) which comprises interpenetrating sublattices of frustrated quasi-one- dimensional s=1/2 quantum Heisenberg magnetic Cu2+ chains and frustrated quantum Ising electric sublattice of LiI ions. Incommensurate spin order occurring in this compound at TNâ6 K gives rise to a drastic change of the 7Li NMR Spectrum. We show that the peculiar NMR line shapes are determined by the specific, sample dependent, distribution of the LiI ions in the glassy ordered electric sublattice. The analysis of the NMR data in the framework of a spin-spiral model gives evidence for a remarkable interaction between magnetic and electric degrees of freedom in γ-Li2ZrCuO4, which suggests it as a promising model compound for fundamental studies of complex magnetoelectric phenomena and illustrates well their richness. © 2013 American Physical Society
