Wataru Ando – 1st expert on this subject based on the ideXlab platform

  • Lithium-Bridged Bis(silyl anion) of 9,10-Dimethyl-9,10-disilaanthracene.
    Chemistry Letters, 1997
    Co-Authors: Ken Hatano, Kenji Morihashi, Osamu Kikuchi, Wataru Ando

    Abstract:

    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
    , 2005
    Co-Authors: Li Zi-rong, Xue Rongjian, Chen Liquan

    Abstract:

    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.
