Unified Theory of Photochemical Charge Separation

Contact and Distant Luminescence Quenching in Solutions

“…are exactly the same as in the spinless theory [9]. How these quantities are affected by spin-conversion, either coherent or incoherent, will be discussed later in the frame of the unified theory (Section 5.5).…”

“…Such a diffusional dependence of the yields is natural for the archaic "exponential model" which implied that Z = z = const [9,16]. Though incorporated into the encounter theory, the recombination efficiency Z(r 0 ) becomes the function of not only D but also r 0 , while Z appears to be dependent on both D and D. Two factors determine the type of this dependence: the shape of the recombination layer and the location of the starting point.…”

“…Although DET covers only the irreversible transfer, it is known to be exact in the particular case of the target problem (immobile A * quenched by independently moving point B's) [9]. In the simplest case the time-dependent reaction constant of DET substituted for its contact analog (2) has the following definition: k A (t) = W A (r)ν(r, t)e t/τA d 3 r .…”

“…It reduces the coherent description of density matrix evolution to the incoherent one which substitutes the phenomenological ESM set (102) by the more appropriate one [9,68,69]:…”

Fluorescence Quenching by Reversible Charge Separation Followed by Ions Recombination and Their Separation Suppressed by Coulomb Attraction

“…where and 0 are static and optical dielectric permittivities [5]. The reversibility of electron transfer is accounted for by a correction term in the denominator of (20), where…”
