Chromophore/DNA interactions: femto- to nanosecond spectroscopy, NMR structure, and electron transfer theory
Article Abstract:
The mechanism of photoinduced hole injection into DNA is analyzed by using an integrated approach that has combined NMR structural analysis, time-resolved spectroscopy and quantum-chemical calculations. The studies have justified the appreciable neglect of differences of electronic couplings as well as in the reorganization energy in 5'-GAX and 5'-ZAG.

Are radical cations states delocalized over GG and GGG hole traps in DNA?
Article Abstract:
The effects of solvation and internal reorganization on the hole charge distribution in sequences 5'-X-GG-Y-3' are reported. Radical cation states in DNA are localized to a single guanine site independent of the nature of adjacent base pairs.
