Abstract	Infrared and Raman spectra of cristobalite are presented as a function of temperature through the phase transition. The modes are assigned and the assignments compared to those of earlier workers. The compatibility of modes at the G-point of the a-phase with the X and G-points of the �-phase is given. In the transition region of ca. 500�550 K, smooth changes in intensity, frequency and linewidths are seen in many modes, indicative of coexistence of a- and �-forms.
