Abstract：
The Multicomponent heteropoly compounds [Me4N]3+x[PVxMoyW 12-x-yO40] .n (H2O) with Keggin structure have been synthesized, and have been characterized by FTIR and NIR FT-Raman. The vibrational regularity of oxygen-containing bonds (P-Oa, M=Od, M-Ob-M and M-Oc-M) in these heteropoly compounds have been studied. The vibrational frequencies νas (M= Od) and νas (M-Ob-M) was shown to prove the reason why the acidity of the heteropoly compounds descended and the oxidization increased by the substitution of V atoms.
