## EXPERIMENTAL The IR and Raman spectra of a single crystal The crystals were prepared by the slow evaporation of NH 4 Sm(SO 4 ) 2 ؒ 4H 2 O and that of two polycrystalline compounds NH 4 Ln(SO 4 ) 2 ؒ 2H 2 O [Ln ؍ Yb, Tm] have been recorded and an aqueous solution containing lanthanide sulfate
The water activities and osmotic coefficients of aqueous solutions of {(NH 4 ) 2 SO 4 + Li 2 SO 4 } and {(NH 4 ) 2 SO 4 + Na 2 SO 4 } have been determined at a temperature of 298.15 K with a hygrometric method, at molalities in the region 0.2 mol • kg -1 to saturation of the solutes for different fr
