Project 5: Acid-base & redox properties of heteropoly compounds
要旨:
The problem of optical spectra of dodecanuclear clusters with the Keggin structure is considered. Charge-transfer and d-d -bands arising from intact and ill-defined species formed on different stages of disintegration of the heteropoly acid H4PVMo11O40y H2O are investigated in detail. On the basis of the performed calculations the transformation of optical spectra of H4PVMo11O40 yH2O under increasing temperature and time on stream is explained.
