Abstract
Polarized Raman spectra obtained from carefully characterized single c rystals of ZnIn2S4, Zn2In2S5, and Zn3In2S6 are reported. The low-frequ ency Raman spectra clearly differentiate between the compounds, wherea s at high frequencies the vibrational features are less sensitive to t he actual crystal structure. The results are interpreted on the basis of a molecular-like picture based on the intrinsic cationic disorder.
