Which B is a n-Pair Donor

Angular Geometries of B- -CIF and B -HCI in Which B is a Mixed n-Pair/n-Pair Donor... 

Fig. 28 Photoinduced electron transfer studies carried out on 6-mer (not shown) and 7-mer hairpin DNA duplexes capped by a stilbene acceptor chromophore.31 167 168 The duplexes contain A-T base pairs and a single G-C base pair, whose position in the duplex is varied, (a) The photoinduced ET process is illustrated for 3G C, in which the G-C base pair is third removed from the stilbene (St) group. The stilbene fluorescence is quenched by electron transfer from the G donor, (b) Damping factors for charge separation, /3(CS), and subsequent charge recombination, /3(CR), for n G C, in which the G base is connected to the T-bearing strand, (c) Damping factors, /3(CS) and /3(CR), for n C G, in which the G base is connected to the A-bearing strand.
