| Popis: | The IR and polarized Raman spectra of a single crystal RbAl(SO 4 ) 2 ·12H 2 O is recorded and analyzed at room temperature. Bands indicate a stronger S–O bond in RbAl(SO 4 ) 2 ·12H 2 O than that in a free SO 2− 4 ion. The fraction of reversed sulfate group in the Rb alum is much lower than that in the potassium alum. Broad bands with frequencies considerably shifted from the free state values indicate that water molecules form hydrogen bonds of various strengths. Two crystallographically distinct water molecules are identified in the crystal. |
