Raman spectra have been studied on doped fullerides of BaxC60(x=3,4,6), AxBa3C60(x=0,3; A=K,Rb), and KxSm2.75C60(x=0,3.25). 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.
