Oxide phonon spectra

Abstract

An attempt is made to apply ‘group frequency’ assignments to the vibrational spectra of oxides. The following oxides are considered: TiO₂(both anatase and rutile), SnO₂(cassiterite), ZnO, WO₃, CeO₂, ThO₂, B-Nb₂O₅,V₂O₅, MoO₃, and MoO₃′. The experimental data on V₂O₅(single-crystal Raman study), B-Nb₂O₅(single-crystal Raman study), WO₃, CeO₂, ThO₂, and MoO₃′ are new. There are also additional results for SnO₂ and new i.r. data (including single-crystal studies) on MoO₃.
