A comparative analysis of Raman spectra of barium titanate in various forms is performed over a broad range of temperatures (from 80 to 400 K). In particular, the evolution of A 1 (2TO) and E (1TO) soft‐mode components, sensitive to strain, is monitored for such materials as single crystal, ceramic, and polycrystalline film. Based on the temperature dependence of these components, a sequence of phase transitions is established for each of the aforementioned forms.
