Figure 3. Peak intensity versus electron binding energies for the Cs 3d5/2 photoelectron peaks. Upper solid lines are after washing with D.I. water, lower dashed lines are after washing with 0.1N HCI, lower solid lines are background Cs concentrations.

One of the first tasks of XPS was the precise determination of core electron binding energies for all elements of the periodic table. These data are now tabulated and available for reference (Table 1). On the other hand, there is a great interest in the measurement of the range of low binding energies (0-20 eV) to get a clearer picture about structure and symmetry of the molecular orbitals.

Figure 20-3. Electron binding energies for molecule M in anionic state are defined pictorially in a representation of the potential energy surfaces of the neutral molecule (M) and anion radical (M ) with the lowest vibration energy level shown for each. During a vertical process, the geometry remains unchanged but for the adiabatic process structural relaxation occurs. Thus the VDE (vertical detachment energy) and VEA (vertical electron affinity) represent the upper and lower bounds to the adiabatic electron affinity (AEA)...

In spite of the very simple assumptions leading to this model, it leads to quite acceptable approximate values for electron binding energies for molecular species when compared with some other approximate approaches. This model has been applied under the name Energy Weighted Maximum Overlap (EWMO) to a number of problems involving photoelectron spectra and to a number of problems in the interpretation of spin resonance experiments. 

We might well be tempted to take the molecular orbitals obtained for H2 and put in two paired electrons in the lowest level to calculate the energy of This procedure would predict that if a + p is the electronic binding energy for H2 , then Za + 2p would be the binding energy for Hjj. In fact, the calculated values of a + P for both systems (29.7 e. v. for 1 2 and 26. 5 e. V. for H2) are amazingly...

A means to deposit energy in multiply charged cation complexes is by the exothermic addition of an electron. The technique of electron transfer dissociation (ETD) employs as an electron donor the polycyclic aromatic hydrocarbon fluoranthene anion, CieHio , the electron binding energy for which is only 0.6 eV. An important characteristic of ETD when applied to metal ion complexes is that the process results in both charge reduction and chemi-...
