Binding energy distribution

Fig. 3. Binding energy distribution of several oxygen species occurring on emersed electrodes. Binding energies are taken for different substrates from various authors. In part after [15, 18].

We can now re-interpret the quantity Um)s — Um)o oti the right-hand side of (3.4.7) in terms of structural changes. A more appropriate term would be redistribution of quasi-components. We shall do it in two steps. First, we use the binding energy distribution function xbe introduced in Sec. 2.3. Second, we shall reformulate this quantity in terms of structure as defined in Sec. 2.7.4. Finally, we shall use the same quantity to apply to a two-structure mixture-model approach to water. 

Using the binding energy distribution function xbe(v) defined in Sec. 2.3, we can write the total internal energy of the system as... 

From the binding energies calculated for the different cluster compositions, we determined abundance mass spectra for heated CggLi clusters from a simple Monte Carlo simulation. Figure 11 shows the simulated mass spectra resulting from these calculations, including the Li and Cgo isotope distributions. The peaks at A = 12 and at x = 6 + n (where n is the cluster charge) observed in the experiment (Fig. 9) are well reproduced. For more details, see ref. [12]. 

Fig. 30. Contour plot of photoelectron-photodissociation coincidence spectrum as a distribution of photoelectron intensity (dark shade = low, light shade = high) against the electron binding energy and relative translational energy of the photofragments. Also shown on the left and at the bottom are the partially averaged distributions for the translational energy release and the electron binding energy, respectively.

In Fig. 2 the correlation between the electron distribution curve (EDC) of the solid sample and the distribution of kinetic energies is sketched. The binding energies of the electronic levels can be calculated from the kinetic energy by... 

The distribution of electronic states of the valence band for the colored film at 1.25 Vsce resembles very much the valence band of pure Ir02 as reported by Mattheiss [93], The maximum of the l2g band occurs at 1.6 eV below EF, the 02p region extends from roughly 4 eV to 10 eV and a finite density of electronic states at the Fermi level. Upon proton (and electron) insertion the l2g band, which can host 6 electrons, is completely filled and moves to a binding energy of 2.5 eV. Simultaneously, the density of states at EF is reduced to zero and an additional structure, indicating OH bond formation, occurs in the 02p band. The changing density of states...
