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 low-temperature form of K 3 Sm(PO 4 ) 2 crystallizes in the glaserite type. The Raman and infrared spectra have been investigated: they are consistent with the proposed space monoclinic system [a = 7.4347(5) A ˚, b = 5.6270(5) A ˚, c = 9.4919(5) A ˚, β = 90.870(6)°, Z = 2, space group P2 1 /m].
