Abstract
A27 Al ENDOR study on the vanadyl aquoion adsorbed on hydrous δ-alumina is reported. The observed aluminium hyperfine interaction of 7.2 MHz is interpreted in terms of an inner-sphere surface coordination model. The magnitude of the coupling is attributed to spin delocalization from the vanadyl moiety to surface bound aluminium centers. It is concluded that equatorial positions of the VO 2+ fragment are occupied by surface functional groups. Proton ENDOR spectra confirm the presence of both axial and equatorial water ligands.
