Abstract
Raman-scattering experiments have been carried out on misfit-layer compounds MT (M=Sn, Pb; T=Nb, Ti), in which two types of building layers, MS and T , are stacked 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 modes of relative to those of 2H- is interpreted in terms of a charge transfer from the MS layer to the layer.
