Extra binding-energy data

Valence PES data for [FeCy have been used to probe the MO structure of the ferrous site (Figure 9). The general shape of the photoelectron spectrum is quite similar to that for the ferric species except for a new peak on the low binding-energy side (labeled redox-active molecular orbital (RAMO)). That peak corresponds with the extra electron in the ferrous species, the lone electron in the 3 manifold. Although the overall shapes of the spectra are similar, the variable photon energy behavior is quite different in the ferrous relative to the ferric site. In the ferrous...
