Consider first of all the so-called crystal field transitions these involve moving the b electron to the e, bi, and Iai M.O. s, which are of course essentially the 3d metal orbitals, resulting in E(I), Bi, and Ai exdted states, respectively. To a good approximation dectron repulsion...

The future impact of instrumentation will certainly bring more information about these supermolecular intermediates which might be termed multiplexes [119] or, in anology to inorganic systems, exdted-state organic clusters implying some ordered structure.

The values me and mh are the effective masses of the electron and hole respectively. The second term describes the Coulombic interaction of the electron and the hole, where e is the universal charge and e is the dielectric constant of the material in question. Good correlation between theory and experiment has been obtained within this model for larger nanoclusters [78]. In the case of smaller particles, especially those smaller than 2 nm, the lowest exdted states are located in a region of the energy band that is no longer parabolic and, as a result, the effective mass approximation breaks down. For these partides a more molecular approach re-... 

FIGURE 7. Exdted-state add-base equilibrium of HPTA in MeOH followed by the fluorescence titration of the base form. The base was titrated by trifluoromethanesulfonic acid. Acid band maximum is at 466 nm and base band is at 553 nm. Notice the red shift in the fluorescence spectra compared to the absorption spectra shown in Figure 6 (from Reference 67)...
