摘要：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{mp}{Bj}a{+/-
