 Abstract: The binding of isolated oxygen atoms to small tantalum clusters is investigated using vibrational spectroscopy. Infrared spectra of TanO⁺ 0;1;2 (n=6–11) are reported in the range of 90–1100 cm -1,comprising both the internal cluster modes and the adatom’s vibrations. The vibrational spectra are compared to the results of DFT calculations for n=6–8, which show that the oxygen atoms bind preferentially as 2-fold bridging adatoms. Addition of one or two O atoms induces only minor distortions of the underlying metal cluster core.
