The final rotational state distributions of NO can be qualitatively interpreted as a reflection of the stationary wavefunction at the transition state mediated by the dynamics in the exit channel. Figure 10.13 depicts the total stationary wavefunctions 7 E) corresponding to the en-... 

In addition to the type of electron transfer reaction, shown in Equations 6.142-6.145, there are examples where pure MLCT excited states induce ligand substitutions by associative or dissociative mechanisms. A well-established example of a MLCT excited state-mediated ligand labilization reaction is shown in Equation 6.149.136...

Fig. 46. Band structure model of Cu/Cu20/electrolyte with the space charge layer SCL, the valence band VB, the conduction band CB, and the sub-band SB formed by interband states, mediating electron transfer between the metal to the redox states of the Co(III) complex within the electrolyte. The formation of electron hole pairs by photoexcitation and the transfer of electrons to the empty states of the redox system via surface states SS is also indicated.

Figure 28. Diagram showing the competition between direct and surface state mediated electron exchange between an -type semiconductor and a simple redox system (A = 1 eV). The competition is determined by the effective density of surface states at around the Fermi-level [2 k T s] and the band bending at equilibrium [ cb(0)— //(Ox/Red)]. The demarcation line indicates equal rate of both processes.

Figure 29. Calculated current-potential characteristics for direct (dashed lines, 0/cm ) and surface state mediated electron transfer between an -type semiconductor electrode and a simple redox system. The plots show the transition from ideal diode behavior to metallic behavior with increasing density of surface states at around the Fermi-level of the solid (indicated in the figures). This is also clear from the plots below, which show the change of the interfacial potential drop over the Helmholtz-layer (here denoted as A(Pfj) with respect tot the total change of the interfacial potential drop (here denoted as A(p).
