Abstract：
Two-dimensional correlation infrared spectroscopy (2D-COS) were employed to investigate temperature-dependent spectral variations [(PO4)(2)Mo5O15](6-), beta-[Mo8O26](4-), [PMo12O40](3-), [P2W18O60](6-) cluster anions. Two-dimensional correlation spectra ill 8001000 cm(-1) region provides information about the variations of the terminal Mo=O bonds in the polyoxomolybdenum (or Polyoxotungstic) cluster anions. In 600-800 cm(-1) region, it reveals the information about the variations of the bridging Mo-O-Mo bonds in the cluster anions. The results indicated that the intensity change of the terminal Mo=O bonds are more sensitive than the bridging Mo-O-Mo bands to the temperature variation. Furthermore, from [(PO4)(2)Mo5O15](6-), beta-[Mo8O26] to [PMo12O40](3-), with the cluster anions becoming larger, the 2D-IR spectra showed the bridging Mo-O-Mo bonds in the cluster anions were becoming more sensitive to temperature variation.
