  Raman shift dependence of charge transfer is studied in the two fulleride
families of AxBa3C60 (x=0,3; A=K,Rb) and KxSm2.75C60 (x=0,3.25). It is found
that the Raman spectra are essentially identical to each other for all ternary
fullerides, The results show a crossover point at the boundary of t1u and t1g
bands for the Raman shift dependence of charge transfer. For the t1u
fullerides, the Ag(2) pinch mode follows the characteristic shift of ~6.3cm-1
per elementary charge widely observed in KxC60. The two Ag modes in t1g
fullerides show a complicated behavior. An anomalous Raman shift is observed in
the t1g fullerides. This anomalous Raman shift of the two Ag modes could not be
explained only by charge transfer.
