摘要：

Raman measurements on low stage compounds of graphite intercalated with AsF5, HNO3 and SbCl5 are reported. The spectrum of the stage 1 C8AsF5 acceptor compound is found to be in sharp contrast with that reported for the donor stage 1 C8M(M=K, Rb, Cs) compounds. Whereas the stage 1 donor compounds have been found to exhibit a characteristic broad, asymmetric Breit-Wigner line shape, the spectrum of C8AsF5 contains a single Lorentzian line in this frequency region. Temperature studies of the bounding layer mode lineshape parameters in C8AsF5 showed no evidence of the order-disorder transition in the adjacent intercalate layer. The bounding layer mode frequencies of AsF5, HNO3 and SbCl5 graphite are reported, but no intercalate layer modes were observed. © 1979.
