The polarized Raman spectrum of a dilute solid solution single crystal of Ba 2+ CrO 4 2−doped in KI has been obtained. The polarization data confirm the previous assignments based on infrared absorption investigations alone. The Raman polarization measurements strongly indicate the presence of non‐randomly oriented Ba 2+ CrO 4 2−ion pairs possessing mainly C 2 ν and C s site symmetries.
