Abstract.
Hybrid density functional calculations are performed to study the structural and electronic properties of neutral, anionic and cationic Y3O clusters. The most stable structures of these clusters are found to be triply bridging oxygen atom structures with C S symmetry. The ground states of Y3O, Y3O- and Y3O + are doublet (2A”), triplet (3A”) and singlet (1A’), respectively. The calculated electron affinities and ionization potentials are in good agreement with the available experimental data. Time-dependent density functional theory is used to calculate the low-lying excited states. A theoretical assignment for the features in the experimental photoelectron spectra is given.
