Abstract:
Raman studies on powder samples of C-60.TDAE are reported in the temperature range of 296 to 14 K. The strongest line A(g)(2) shows a doublet at 1454 and 1463 cm(-1) whose relative intensities are strongly temperature dependent. The relative intensities of the H-g(7) and H-g(8) modes at 296 K are much higher than those in pure C-60 and these intensities increase at low temperatures. The phonon softening and broadening are compared with the results on alkali-doped C-60 and the theoretical calculations.
