Abstract
And have been characterized using and magic angle spinning (MAS) nuclear magnetic resonance spectroscopy. was synthesized by a hydrothermal route and was synthesized at high temperature in an inert atmosphere. Both compositions give rise to single isotropic resonances. The MAS isotropic peak linewidth for is considerably larger than that for suggesting the presence of local disorder in the Li coordination sphere for In both samples, the isotropic peak is accompanied by a large, asymmetric spinning sideband manifold, arising from bulk magnetic susceptibility broadening and the paramagnetic interaction between the lithium nucleus and transition metal unpaired electrons. © 2002 The Electrochemical Society.
