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 โข kg -1 to saturation of the solutes for different fr
Infrared and polarized Raman spectra of (NH4)JH(S04)1 have been recorded and analysed. Multiple bands are observed for the vibrational modes of SO:-and NH: groups. HSO; and SO:-ions are found to coexist with vibrational interaction between them. NH: ion is not rotating freely in the lattice.
The Raman spectra of polycrystalline were investigated in the range 300-450 K. An RbH(SO 4 ) 0.81 (SeO 4 ) 0.19 assignment of bands due to internal and external vibrations in terms of approximate types of motions is proposed. The spectral data are used for discussing the nature of structural disorde
