We explore charge migration in DNA, advancing two distinct mechanisms of charge separation in a donor (d)-bridge ([Bj])-acceptor (a) system, where [Bj] = B1,B2, . , BN are the N-specific adjacent bases of B-DNA: (i) two-center unistep superexchange induced charge transfer, d*[Bj]a --> d[Bj]a+/-, and (ii) multistep charge transport involves charge injection from d* (or d+) to [Bj], charge hopping within [Bj], and charge trapping by a. For off-resonance coupling, mechanism i prevails with the… CONTINUE READING
