The size-dependent influence of palladium doping on the structures of cationic gold clusters.

ABSTRACT: The physicochemical properties of small metal clusters strongly depend on their precise geometry. Determining such geometries, however, is challenging, particularly for clusters formed by multiple elements. In this work, we combine infrared multiple photon dissociation spectroscopy and density functional theory calculations to investigate the lowest-energy structures of Pd doped gold clusters, PdAu _n-1 ⁺ (n ≤ 10). The high-quality experimental spectra allow for an unambiguous determination of the structures adopted by the clusters. Our results show that the Pd-Au interaction is so large that the structures of PdAu _n-1 ⁺ and Au _n ⁺ are very different. Pd doping induces a 2D to 3D transition at much
