Title: Structural Characterization of Unprecedented Al<sub>14</sub>O<sup>–</sup> and Al<sub>15</sub>O<sub>2</sub><sup>–</sup>: Photoelectron Spectroscopy and Density Functional Calculations
Abstract: New aluminum oxide clusters Al14O– and Al15O2– were observed unprecedentedly in the gas-phase reaction of Aln– and O2. Photoelectron spectroscopic measurements and density functional calculations indicated that Al14O– and Al15O2– are composed of an icosahedral Al13 moiety bonded by one and two OAl unit(s), respectively. The preferential formation of Al14O– and Al15O2– is explained in terms of the high stability associated with the Al13 moiety and efficient collisional trapping as intermediates of oxidative etching reactions.
