We report an experimental and theoretical investigation of the electronic and optical properties of a series of icosahedral Au<sub>13</sub> nanoclusters, protected using different halogen ligands (Cl, Br, and I), as well as 1,2-bis(diphenylphosphino)ethane (dppe) ligands. All three clusters are comprised of the same Au<sub>13</sub> kernel with two halogens coordinated to the poles of the icosahedral cluster along with five dppe ligands. UV-vis absorption spectra indicate a systematic red shift f ...[more]
