NMR of Li-doped C-60 polymers

摘要

We report NMR studies on Li-C-60 compounds heated under high pressure. For LiC60 and Li4C60, C-13-NMR showed the presence of sp(3) carbon atoms in the crystals, indicating the transformation to C-60 polymer phases. It was also shown by Li-7-NMR that the Li-atoms are moving in the crystal at room temperature. [References: 7]
