摘要
IR and Raman spectra of KCe(SO4)2.4H2O and NaCe(SO4)2.4H2O are recorded and analysed. The bands indicate a crystal structure similar to those of NH4La(SO4)2.4H2O and NH4Ce(SO4)2.4H2O in these compounds. SO42- ions are largely distorted in the compounds. Three crystallographically distinct water molecules exist in the unit cell.
