Bulk C60 has been treated at 1.1 GPa and 550-585 K, producing a dense insoluble material which on heating to above 600 K reverts to normal C6o. Raman and IR studies on modified material show a large number of new lines, and the Raman pentagon pinch mode shifts from 1469 to 1458 cm-1 as on photopolym

Raman scattering is used to study the thermal decomposition of photochemically produced polymeric Cso films. Under the experimental conditions, a steady state monomer population is maintained through a competition between: (a) the photoattachment of monomers to other monomers and higher oligomers (e
We report measurements of thermal conductivity in 30-350 K range of hard fullerene-based carbon. The material has been prepared from C6o fullerene under pressure and has an unusual combination of large hardness and relatively high electrical conductivity. Its thermal conductivity is about 5.5 W/mk a
Packing models of three polymeric phases of C 60 obtained through pressure-temperature treatments have been reconsidered through a lattice energy minimization method using atom-atom potentials. Orthorhombic phase O, previously assigned Immm symmetry, is best described by space group Pmnn. Whereas th
