Scholarcy highlights

  • Raman spectra of anatase have been observed in natural and synthetic crystals
  • The Raman band occurring at 516 cm−1 at room temperature is split into two peaks centred at 519 cm−1 and 513 cm−1 at low temperature
  • The six Raman active fundamentals predicted by group theory are all observed and assigned
  • The spectra are analyzed by a simple model considering only short-range forces and the calculated vibrational frequencies are in good agreement with the observed Raman frequencies
