Calculations by the semiempirical theoretical method ASED-MO of the photodimerization of cyclohexene and methane by decatungstate anions have been carried out [84], Calculated hydrogen abstraction activation energies for a C-H bond in methane are higher than for cyclohexene, but they are low enough that in the case of methane it can be suggested that dimerization could be looked for in future experiments.

IR spectra confirmed the formation of decatungstate anions in the W04 -HCI-DMF-H2O system. Raman spectroscopy was used to probe the high-temperature (600-800 K) phase transitions in incommensurate RbW04. IR... 

We discuss here two examples of vibronic effects in polynuclear highly symmetrical transition metal clusters. The existence of degenerate and quasi-degenerate molecular orbitals in their energy spectra results in the Jahn-Teller effect or in the vibronic mixing of different electronic states. We show that both quantum-chemical methods and model approaches can provide valuable information about these vibronic effects. In the case of the hexanuclear rhenium tri-anion, the Jahn-Teller effect is responsible for the experimentally observed tetragonal distortion of the cluster. The vibronic model of mixed-valence compounds allows to explain the nature of a transient in the photo-catalytic reaction of the decatungstate cluster. 

In cationic polymerization, the use of decatungstate (Wio032" ) anion in combination with silanes has been fonnd to allow the generation of silyl radicals by irradiation by green flnorescence bulbs or simply by exposing to...
