| Popis: | Les spectres Raman et Infrarouge des phosphates de cuivre de type Nasicon CuIM2(PO4)3, CuII0,5M2(PO4)3et H0,5CuI0,5M2(PO4)3(M= Ti,Zr) ont ete etudies. Une analyse de groupe facteur a permis de preciser les modes internes de l'anion PO3−4. Des diagrammes de correlation pour differentes symetries du site de PO4dans le type structural Nasicon ont ete proposes. L'evolution des spectres est correlee avec celle de la structure Nasicon. The Raman and infrared absorption spectra of Nasicon-type copper phosphates with formulas CuIM2(PO4)3, CuII0.5M2(PO4)3, and H0.5CuI0.5M2(PO4)3(M= Ti,Zr) have been investigated. A factor group analysis leads to determination of internal modes of the PO3−4anion. Correlation diagrams for various site symmetries of PO4in the Nasicon-type structure have been proposed. The evolution of the spectra is discussed in relation with the structure. |
