摘要：

Differential Scanning Calorimetry (DSC), a.c. electrical conductivity and infrared spectroscopic measurements on crystalline Rb4H2(SeO4)3 have been performed. A large endothermic peak in the DSC at 377 K supported by a sudden jump in the conductivity plot, confirms the presence of a phase transition at this temperature. Infrared spectra at various temperatures show a change in the internal mode frequencies on heating.
