摘要：

The 18 vibrational modes expected from group-theoretical analysis have been obtained in the polarized Raman spectra of ZnWO4 single crystals. The six internal modes of the WO6 octahedra have been assigned, The temperature dependence of the frequencies and linewidths of the internal modes is related to anharmonic terms in the crystal potential.
