Electron self-exchange collisions

Hence, by measuring the rate of electron self-exchange, one can readily use the Marcus model to calculate the reorganization energy X. To evaluate this, a collision frequency ofZ 10nM s is generally used, and the temperature is given in Kelvin. 

Increasing Q, would decrease the average minimum distance between a self localized PFq.fast excitation and a possible CTS defect, which suggests that Eq. 4, simply describes the qualitative dependence with distance for the Dexter electron exchange mechanism k j = ko e R, where ko is the maximum rate constant for energy transfer, occurring when donor and acceptor are at the collision distance Ro and R is the separation between donor and acceptor when they are further apart than Ro.
