| Abstract: | Normal coordinate treatments of NbW5O19 3- and MoW5O19 2-, two polyoxoanions related to the Lindqvist structure, were performed by assuming the transferability of the internal force field of the parent hexatungstate W6O19 2-. The valence force fields were discussed according to the nature of the M' atom (Nb (V) or Mo (VI)) considered as a perturbing element in the tungstic framework. |
