Spectroscopic study of pressure-polymerized phases of C-60

Comparative studies of the infrared (IR) and Raman spectra of the orthorhom bic, tetragonal, and rhombohedral pressure-polymerized phases of C-60 as we ll as the pressure-dimerized state have been performed at ambient condition s. The tentative assignment of the vibrational spectra of different phases has shown that they could be perfectly described by the molecular symmetry of the C-60 polymers which are the structure-forming elements of crystallin e polymerized phases. This allowed one to consider the IR and Raman spectra of the crystalline polymerized phases as characteristic of these of the ap propriate one- and two-dimensional C-60 polymers and to use them for molecu lar fractional analysis of polymerization products.
