The vibrational spectra of the cage compounds P4S3, P4Se3 and AS4S3 have been recorded in the solid and the molten state. The vibrational spectra of crystalline As4Se3, which decomposes during melting, have been investigated. The frequencies wore assigned using the concept of group frequencies. A new assignment of the Raman frequencies is proposed for P 4 S 3 based on new polarization data. The frequencies of the arsenic compounds are reported for the first time. The Raman spectra of the molten compounds suggest that the cage structure is retained in the molten state.
