Electron spin density distribution in the polymer phase of CsC60:: Assignment of the NMR spectrum

We present high resolution Cs-133-C-13 double resonance NMR data and C-13-C-13 NMR correlation spectra of C-13 enriched samples of the polymeric phase of CsC60. These data lead to a partial assignment of the lines in the C-13 NMR spectrum of CSC60 to the carbon positions on the C-60 molecule. A plausible completion of the assignment can be made on the basis of an ab initio calculation, The data support the view that the conduction electron density is concentrated at the C60 "equator," away from the interfullerene bonds.
