The Raman spectra of single crystals of NaPF 6 ·H 2 O are reported. By transferring the Raman tensors for the O h point group to the NaPF 6 ·H 2 O crystal, the relative intensities of the PF 6 −modes are calculated and a good agreement is obtained between the calculated and observed values. The Raman tensors for the internal modes of the water molecules in NaPF 6 ·H 2 O are obtained and it is shown why the totally symmetric bending mode of these molecules is not observed in the Raman effect. The ratio of ∂α/∂ S 1 values for the PF 6 −and H 2 O groups in this study corresponds to the one calculated from a delta potential function.
