The Raman spectra of sixteen compounds derived from HN(SO 3 ) 2 2− have been compared. The results show that the substitution of one or more of the oxygens of the original tetrahedron SO 4 2− by a ligand F, Cl, NH, N, implies a contraction of the free SO bonds. This is characterized by the shifting of the symmetrical stretching frequency ν s (SO). The polarizing power of the associated cations can also affect ν s (SO).
