## Abstract The mode assignment of the cubic phase of anhydrous Na~2~MoO~4~ was carried out on the basis of lattice dynamic calculation using the classical rigidβion model. Temperatureβdependent studies indicate that this crystal remains in the cubic structure in the 15β773 K range and undergoes a

Successive phase transitions in CsBi(MoO 4 ) 2 at 125 and 325 K have been studied by Raman spectroscopy. The changes in the crystal structure, induced by the low-temperature first-order transition, have been discussed. The found anomalous shifts of some internal modes towards lower frequency with de
## Abstract We have measured polarized Raman spectra of MnWO~4~ single crystals at low temperatures, and studied the temperature dependence of the various phonon modes. From our Raman studies of the MnWO~4~, a new transition temperature, βΌ180 K, was found. We have completely assigned the symmetries
