摘要
Polarized IR and Raman spectra of NaBi(MoO4)(2), NaBi(WO4)(2) and LiBi(MoO4)(2) single crystals were measured at room-temperature in the range of 580-1000 cm(-1) and 20-1000 cm(-1), respectively. In general, the recorded spectra are similar to the spectra of simple molybdates and tungstates. However, the polarization characteristics of the double molybdates and tungstate studied is different. The results obtained we interpret by assuming the existence of some short-range order in these structures.
