Results of a micro‐Raman spectral investigation of K + ‐doped BaSO 4 crystals prepared by a previously described radiochemical coprecipitation procedure are reported. Changes in the spectral bands of the ν 1 , ν 2 , ν 3 and ν 4 modes of the sulphate ion as a function of K + concentration in the BaSO 4 crystals reflect changes in the local environment of the SO 4 2− ion indicating mixed‐crystal formation. These preliminary results show that Raman spectroscopy can be used to characterize changes in the BaSO 4 lattice due to coprecipitated impurities.
