Abstract
Sb5O7I undergoes a displacive phase transition at 481 K where the symmetry is changed fromC 6h 2 toC 2h 5 . In the low temperature monoclinic phase the crystal is ferroelastic. The polarized Raman spectra of Sb5O7I have been measured at various temperatures below and above the phase transition. The frequencies and symmetries of most of the theoretically expected Raman active phonons in the ...
