The 1st spectral peak of a and b, 925 and 918 cm-1, respectively, could be assigned to the terminal W-O. The 2nd peaks (876 and 875 cm-1) and the 3rd peaks (763 and 765 cm-1) of a and b also could be allocated to the corner-sharing W-O-W and the edge-sharing W-O-W, respectively. The similarity of the FTIR spectra indicated that a and b have similar structures. |

1. a and b have similar FTIR spectra (¦Í= 925, 876, 761 cm-1 for a, and ¦Í= 918, 875, 763 cm-1 for b) 2. The spectral peaks at 925 cm-1 and 918 cm-1 could be assigned to terminal W-O. The peaks at 876 cm-1 and 875 cm-1 and those at 763 cm-1 and 765 cm-1 could be attributed to corner-sharing W-O-W and edge-sharing W-O-W respectively. 3. The similarity of the FTIR spectra indicated that a and b had similar structures |
