Sometimes the quencher species is not the analyte itself, but a third (non-luminescent) partner, the concentration of which is set by the analyte level. For instance, the pH value (analyte) determines the amount of energy accepting dye that quenches the luminescence from the indicator by an energy transfer process. 

The first direct time-resolved evidence for energy transfer from an upper excited triplet state in solution at room temperature was published in 1987 [50]. This study made use of the two-color technique to photoexcite the 7, state of benzophenone, 70, in benzene solvent. As the extensive (almost quantitative) triplet depletion was not accompanied by any product formation, it was concluded that the excitation energy was transferred to the triplet manifold of the benzene solvent. The energetics of this donor-acceptor system are certainly conductive to this process. The benzophenone 7, and Tn energies (69 kcal/mol and ca. 120 kcal/ mol, respectively—the second photon in the two-color excitation provides roughly 50 additional kcal/mol to the 71 state) bracket the benzene 7j energy (85 kcal/mol) and therefore benzene acts in the same way toward benzophenone as 1,3-cyclohexadiene acts toward anthracene, i.e., as an exclusive upper triplet energy accepter.

When one of the binary processes is energy-accepting (i.e., AH >0), the other is always energy-donating (i.e.,AH < 0). By denoting the direction factors of both processes by Dha and Dhd, respectively, the above equation reduces to...

As it has been discussed previously, for the 2 suns CPC the collected UV radiation is about 75% of the available solar radiation, while a nonconcentrating CPC captures in principle all the available radiation. However, as the aperture area of the 2 suns CPC is twice the aperture of the one sun system, the net result is that it collects 1.5 more energy. In the same way, the 1.5 and 1.75 suns reactors are able to capture 1.4 and 1.25 times more energy than the 1 sun system, respectively. The effect of these differences in the energy accepted by each system can be clearly seen in the degradation of carbaryl (Figure 14), where degradation proceeds faster as the concentration ratio increases. 

In the Monte Carlo simulations of the chromatographic and related processes we should also account for the new knowledge about the deep heterogeneity of surfaces, about the role of localized adsorption and about the occurrence of surface diffusion. Evidently, now the molecular desorption energy accepted for a concrete simulation is to be understood as the effective value over the spectrum of possible energies in the sense of Eq. 5.71. As such, it is related to a concrete form of the p(E ). The...
