TL;DR: In this paper, the infrared and laser Raman spectra of the Sr2V2O7 were analyzed by means of a site symmetry analysis and the principal force constants as well as the mean amplitudes of vibration for the V2O74− ion were calculated using a simplified molecular model.
Abstract: The infrared and laser-Raman spectra of Sr2V2O7 are reported and discussed by means of a “Site Symmetry” analysis. The principal force constants as well as the mean amplitudes of vibration for the V2O74− ion have been calculated using a simplified molecular model. Some aspects of the vibrational behaviour of the V−O−V bridge in this ion are also discussed.

Abstract: Infrared spectra of crystalline Co3(VO4)2, Ni3(VO4)2 and Zn3(VO4)2 as well as the laser-Raman spectrum of the last mentioned compound are reported and discussed. A series of solid solutions of the type (Zn/Ni)3(VO4)2 have also been prepared and investigated, in order to obtain a wider insight into the spectroscopic behaviour of this class of compounds in the 500-250 cm−1 region. Comparisons with the formerly investigated isotypic Mg3(VO4)2 allows to confirm some of the earlier statements and assignments in the light of additional experimental information.

TL;DR: In this paper, the mean amplitudes of vibration for ReOF4 and ReOF5 were calculated from spectroscopic data in the temperature range between 0 and 1,000 K. The results are briefly discussed, some comparisons are made with structurally related species and certain aspects of the bond properties are analyzed.
