Energy Configuration Diagram. This model, based on the energy level diagrams of atoms and molecules, is applicable to luminescence processes in which excitation and emission take place at the same luminescence center. 

The conceptual framework that is used to understand thermal and photoinduced electron transfer is illustrated by a classical potential energy-configuration diagram. The simpliest case for electron transfer in which the electron is coupled between donor and acceptor by a single oscillator having the same frequency in both the initial and the final states is illustrated in Figs, la and lb.

Figure C2.16.6. The energy states of a metastable and bistable muonium in Si are illustrated in a configuration diagram. It plots the defect energy as a function of a coordinate which combines position and all the relaxations and distortions of the crystal. The specific example, discussed in the text, illustrates acceptor and donor levels, metastability, bistability and negative- U [50] behaviour.

The ionization energies and impurity levels are shown in the flat-band figure next to the configuration diagram. 

Turn back to Figure 15-11, the energy level diagram of a many-electron atom, and consider the occupied orbitals of the element potassium. With 19 electrons placed, two at a time, in the orbitals of lowest energy, the electron configuration is... 

The molecular orbital energy-level diagrams of heteronuclear diatomic molecules are much harder to predict qualitatitvely and we have to calculate each one explicitly because the atomic orbitals contribute differently to each one. Figure 3.35 shows the calculated scheme typically found for CO and NO. We can use this diagram to state the electron configuration by using the same procedure as for homonuclear diatomic molecules. 

Sei f-Test 3.1 IB Write the configuration of the ground state of the cyanide ion, CN, assuming that its molecular orbital energy-level diagram is the same as that for CO. 

The third way to represent an atomic configuration uses an energy level diagram similar to the one shown in Figure 8-9 to designate orbitals. Each electron is represented by an arrow and is placed in the appropriate orbital. The...

C08-0057. The ground state of V has lower spin than that of Cr. Construct energy level diagrams for the valence electrons that show how electron configurations account for this difference.

Fe(NH3)e] " is paramagnetic, but [Co (NH3)g is not. Write the electron configuration for each of these metal complexes and draw energy level diagrams showing which has the higher 4. 

Fig. 4. Energy level diagrams showing possible electronic configurations for positively-charged polaron (a) and bipolaron (b) defects and (c) a schematic bipolaron band model. The negatively-charged polaron would carry three electrons and the bipolaron four. Also shown is the neutral polaron-exciton (d) which would decay to restore the chain structure.
