Hyper-Raman scattering has been measured on vitreous boron oxide, v-B₂O₃. This spectroscopy, complemented with Raman scattering and infrared absorption, reveals the full set of vibrations that can be observed with light. A mode analysis is performed based on the local D₃ₕ symmetry of BO₃ triangles and B₃O₃ boroxol rings. The results show that in v-B₂O₃ the main spectral components can be successfully assigned using this relatively simple model. In particular, it can be shown that the hyper-Raman boson peak arises from external modes that correspond mainly to librational motions of rigid boroxol rings.
