Abstract

Raman scattering experiments have been performed on ferroelastic CsIO4 over the temperature range 323K to 200K during cooling and heating cycles. The spectra display marked changes at 256K and 244K during the cooling cycle and at 287K and 291K during the heating cycle. The transition at 256K is suggested to be from normal to incommensurate phase which changes over to a commensurate structure at 244K.
