The structures of isoploymolybdate(VI) were investigated by using laser Raman spectroscopy. The assignment of the Raman spectra showed presence of the [Mo36O112(H2O)16]8- in the 0.2 M HNO3 and the [Mo2O5(H2O)]2+ in the 1.0 M HNO3. To extract the spectrum of the intermediate species, we applied chemometrics analysis to a series of the observed spectra. The analysis revealed presence of one intermediate [Mo(VI)mOy]p species in the 0.5 M HNO3. The intermediate species were assigned to [Mo18O56(H2O)8]4- with the aid of X-ray absorption spectroscopy
