Figure 3: Spectra of the full Au144(SR)60 cluster and partial structures.

From: Information on quantum states pervades the visible spectrum of the ubiquitous Au144(SR)60 gold nanocluster

Figure 3

The absorption cross-section of the full Au144(SR)60 cluster, with R=CH3 (left image), is compared with that of the Grand Core of 114 Au atoms (right), and to that of the ad hoc structure consisting of all 144 Au atoms of the full cluster (middle image). The ligands are defined to include both the Au ad-atoms and the thiolate groups.
