摘要：

We studied the dependence of the Raman depolarization ratio in a C-60/C-70 film within the temperature interval 20-300 K. The experimentally determined RDR is compared with that expected from the corresponding Raman tensors for the low-(s.c.) and high- (f.c.c.) temperature phase of solid C-60. We demonstrate that RDR can be successfully used for detection of subtle C-60-mode-splitting in insufficiently resolved spectra. (C) 1999 Published by Elsevier Science Ltd. Ail rights reserved.
