Abstract
The IR and Raman spectra of Mg orthovanadate Mg3(VO4)2, Mg pyrovanadate Mg2V2O7 and Mg metavanadate MgV2O6 powders are reported, described and discussed on the basis of the crystal structures of these phases and of the optical activity of the fundamental vibrational modes predicted with the use of the correlation method. The IR-active combinations are also discussed. The structural and vibrational features of these compounds are discussed in relation to those of other V-based oxidic catalytic materials.Keywords
