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.
