The IR and polarized Raman spectra of SrC4H4O6 · 3H2O have been recorded and analysed. The factor group analysis of the divalent tartrate ion has been carried out on the basis of C2 symmetry. As the ion possesses lower symmetry in the crystal, splittings have been observed for the different vibrational modes. Separate bands in the bending region of water suggest the existence of three crystallographically different water molecules in the crystal, which is confirmed by deuterium substitution.
