A wide-spread opinion regarding the paratellurite (α-TeO ₂) lattice as a parent structure of TeO₂ glass is questioned. Consequently, the Raman and infrared spectra of TeO₂ glass are contrasted with those of three crystalline lattices (α, β, γ) of TeO₂ and their vibrational state density distribution functions. Additionally, the data on the crystallization of the liquid and glassy states of TeO₂ are considered. As a result, of the known crystalline phases of TeO₂, the γ-phase is proposed as the closest to TeO₂ glass.
