Abstract

Polarized Raman spectra of single crystals of $KIO_4$ and $RbIO_4$ were obtained. The observed fundamental modes satisfy the selection rules valid for the scheelite structure. The pressure dependence of the Raman spectra of $KIO_4$, which was investigated up to 12 Gpa, reveals a structural phase transition in the crystal near 6.5 GPa, where new peaks are observed. Above 9.8 GPa only the peaks belonging to the high-pressure phase exist.
