| Abstract: | The IR and Raman spectra are measured and analysed for sodium pyrophosphate decahydrate. The spectra are interpreted on the
basis of P2O
7
4−
ion and water vibrations. The observed results fit with the features predicted for the factor goup model. The appearance
of two sets of frequencies in the stretching and bending regions of water suggests the existence of two kinds of water molecules
in the crystal. This is confirmed by deuterium substitution. |
