Raman spectroscopy has been used to distinguish structural differences between α-12-heteropoly anions and β-12-heteropoly anions in solution. The results are consistent with the Keggin structure for the α-isomers and a modified Keggin structure for the β-isomers. Reduced 12-molybdophosphates and molybdovanadophosphates in solution have also been characterized by Raman spectroscopy; the results are consistent with a retention of the Keggin structure.
