Abstract: Raman spectra of LiCsSO4 were performed for pressures up to 13.5 GPa. Several modifications in the spectra are interpreted as due to a structural phase transition occurring at 3.8 GPa. This transition is reversible and both directions are fast, in agreement with the general criteria for polyhedral tilt transitions. Pressure coefficients of Raman modes are given. © 1995 The American Physical Society.
