K. Kamaras et al., INFRARED-SPECTRA OF ONE-DIMENSIONAL AND 2-DIMENSIONAL FULLERENE POLYMER STRUCTURES - RBC60 AND RHOMBOHEDRAL C-60, Physical review. B, Condensed matter, 55(17), 1997, pp. 10999-11002
We compare the infrared spectra of two types of fullerene polymers: th
e linear-chain RbC60 and the two-dimensional pressure-polymerized rhom
bohedral C-60. Both the splitting of the F-1u modes and the structure
of newly activated Lines are in agreement with fully ordered structure
s of molecular symmetry D-2h and D-3d, respectively.
