Electron spectraC 2515 Photoelectron Spectroscopy of Free Polyoxoanions Mo6 and W6 in the Gas

Phase. — The gas phase title anions are characterized by photoelectron spectroscopy and DFT calculations with relativistic effective core potentials. Excellent agreement between theory and experiment is obtained. Despite the expected strong intramolecular Coulomb repulsion due to the presence of two negative charges, both dianions are ex-tremely stable gaseous species. — (YANG, X.; WATERS, T.; WANG, X.-B.; O'HAIR, R.
