Figure 4.7. A continuation of Figures 4.5 and 4.6 for the largest clusters studied showing model() and experimental() ionization potentials. The correspondence is still significant although there is less structure in the experimental values. This may be due to the difficulty of resolving large non-isotopically pure silver clusters through mass spectroscopy. The step at 74 is not predicted although 74 is predicted to have a high IP. This is a result of a structural transition that occurs in this region.
