抄録

Raman spectra have been studied on doped fullerides of Ba_xC₆₀(x=3,4,6), A_xBa₃C₆₀(x=0,3; A=K,Rb), and K_xSm_2.75C₆₀(x=0,3.25). The results show different charge-transfer dependence of Raman shift of the two A_g modes in the t_1u and t_1g fullerides. Raman shift of A_g(2) mode with charge transfer in t_1g fullerides does not follow a simple extrapolation from the low-doped t_1u fullerides.

The results show different charge-transfer dependence of Raman shift of the two Ag modes in the t1u and t1g fullerides. Raman shift of Ag(2) mode with charge transfer in t1g fullerides does not follow a simple extrapolation from the low-doped t1u fullerides.
