摘要：

Polarized Raman spectra of single crystals of KIO4 and RbIO4 were obtained. The observed fundamental modes satisfy the selection rules valid for the scheelite structure. The pressure dependence of the Raman spectra of KIO4, 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.
