摘要：
We discuss the structural and dynamic properties of C-60 polymerized under low-P, low-T conditions, and suggest that the disordered mixed orthorhombic-tetragonal-rhombohedral phases produced under these conditions arise from nucleation of molecular chains in random directions because of the quasi-free molecular rotation under standard reaction conditions in the fee phase of C-60. Polymerization in He gives results qualitatively different From those obtained in other media. (C) 1998 Elsevier Science Ltd. All rights reserved.
