Copper energy level diagrams

Figure 13. Left ligand field energy-level diagram calculated for plastocyanin. Center contains energies and wavefunctions of the copper site. Energy levels determined after removing the rhombic distortions to give and C symmetries are shown in the left and right columns, respectively (from Ref. 11). Right electronic structural representation of the plastocyanin active site derived from ligand field calculations (from Ref. 11).

Fluorescence from a six-coordinate copper(II) complex is quite rare and it is easy to see why from the energy level diagram of Fig. 7. If the CuF center is distorted from an octahedral geometry then the lowest level of the T2g multiplet comes very close in energy to the upper sheet of the E <8) e Jahn-Teller surface. For positive Qg in Fig. 7 this is the z excited state, and will offer an efficient... 

A general, schematic energy level diagram for structures 56 -60, where the main photodeactivation paths are reported, is shown in Scheme 12. We have made use of the same type of nomenclature adopted in this presentation the generic array containing zinc(II) porphyrin(s), copper(I) bisphenyl phenanthroline and a 50 moiety is named PZn-Cu-C6o> which allows us to easily identify each component and the transfer of energy or electrons between the units the reaction paths are identified with numbers.

Figure 23 presents an energy band diagram which is based on data derived from the variety of physical investigations. It indicates the structure of the energy bands of the single layers the CU2O surface window layer, the Cu S absorber layer, and the CdS collector layer with deep levels at the interface due to copper diffusion from the CuxS layer.
