  • Abstract
    The hole transfer through DNA was monitored by the transient absorption of radical cation of phenothiazine (Ptz+). The occurrence of hole transfer from G+ generated in DNA to Ptz was observed in the time range of 100 μs. The hole transfer to Ptz was significantly suppressed by introducing oxG as a hole trap in DNA, and the trapping reaction of oxG+ by water was suggested to occur with the rate faster than ∼105 s−1.
