Optical response spectra of AgnCu13−n+ Bernal spiral clusters show subtle variations by dopant site and loading. Comparison to nanorod-like and icosahedral clusters shows local geometry plays a significant role in electronic transitions at the sub-nanoscale.

An understanding of the mechanism of formation of small clusters would help to identify efficient routes to their synthesis. Here, we apply density functional theory (DFT) to study the free...
