The i.r. and Raman spectra of the phases of InVO4 and TlVO4, structurally related to CrVO4, are discussed with the aid of a site symmetry analysis and by comparison with the results obtained for other orthovanadates.

Crystallographic data for the oxoapatites of general formula Ca8Ln2(PO4)6O2 withLn=La, Pr-Ho) have been obtained from X-ray powder data. The vibrational spectra, which are also discussed, allow to make a proposal about the location of the lanthanide cations present in these lattices.

The infrared andRaman spectra of Ba3V10O28·19 H2O has been recorded and an assignement for the internal vibrations of the V10O 28 6− anion is given. Infrared data of the hydrated decavanadates of silver, cadmium, magnesium and lanthanum are also reported and briefly discussed.

Abstract Force Constants of the VO4 3- Ion in the different rare earth orthovanadates of the zircon type have been computed using a modified valence force field and recently reported Raman data. It is shown that the V-O bond strenghtening runs parallel to the unit cell contraction. The Raman spectrum of the tetragonal modification of LaVO4 is reported for the first time.

The infrared spectrum of crystalline K3Nd(PO4)2 is reported and discussed with the aid of a factor group analysis. The electronic spectrum of the solid, in the region of the “hypersensitive” transitions of the Nd(III) ion, is also presented and analyzed.

The infrared spectrum of ScVO4 is reported and discussed in comparison with those of YVO4 and of the lighter lanthanide orthovanadates. In order to facilitate the vibrational assignment the spectra of a series of solid solutions of the type Sc(VO4)1-n(PO4)n are also measured and analyzed.
