摘要：

Raman-scattering experiments have been carried out on misfit-layer compounds MTS3 (M = Sn, Pb; T= Nb, Ti), in which two types of building layers, MS and TS2, are sacked alternately. The spectra obtained from these compounds are regarded as the superposition of the intralayer vibrations of individual layers, which indicates a weak interlayer interaction. The observed Raman shift of the intralayer of NbS2 relative to those of 2H-NbS2 is interpreted in terms of a charge transfer from the MS layer to the NbS2 layer.
