Abstract

Whole scheme of things: The kinetics and efficiency of photoinduced hole transport across DNA A tracts with 1-7 base pairs have been determined from femtosecond transient absorption spectroscopic data. These values are strongly distance dependent over the first four base pairs, but are relatively insensitive to distance at longer distances. These kinetic results (□, ■) parallel the DNA-strand-cleavage results of Giese et al. (○, Black circle). (Graph Presented).
