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 determine
d RDR is compared with that expected from the corresponding Raman tensors f
or the low-(s.c.) and high- (f.c.c.) temperature phase of solid C-60. We de
monstrate that RDR can be successfully used for detection of subtle C-60-mo
de-splitting in insufficiently resolved spectra. (C) 1999 Published by Else
