Kf. Thier et al., NMR INVESTIGATION OF THE ELECTRONIC-STRUCTURE OF THE RBC60 POLYMER PHASE, Physical review. B, Condensed matter, 53(2), 1996, pp. 496-499
We present C-13 high-resolution NMR data on the low-temperature (polym
eric) phase of RbC60. From the temperature-dependent line shift we hav
e extracted information about the hyperfine couplings and electron den
sity distribution on the C-60 molecules. The data also support the exi
stence of an sp(3)-like bonding type between the molecules.
