Energetic control and kinetics of hole migration in DNA
Article Abstract:
A new study investigates two distinct mechanisms for the energetic control and kinetics of hole migration in DNA. The superexchange mechanism and the charge hopping mechanism are examined.

Electronic coupling for charge transfer and transport in DNA
Article Abstract:
Electronic matrix elements for hole transfer between adjacent nucleobases in DNA are calculated. The calculated intrastrand hole transfer matrix elements between adjacent thymines, v+(T, T)=0.16 eV, is seen to be in line with the results of the experiments.

Kinetics of multistep hole transfer in DNA by monitoring the transient absorption of the pyrene radical cation
Article Abstract:
The kinetics of hole transfer in DNA is studied by monitoring the transient absorption of the pyrene (Py) radical cation (Py(super .+)) during the pulse radiolysis of the oligodeoxynucleotides (ODNs) conjugated with Py. The results indicated that the hole transfer in DNA occurred on a microsecond time scale and was dependent upon the DNA sequences and intervening nucleobases between Gs.
