Identification of charge separated states in thymine single strands

Author affiliations

Abstract

UV excitation of the DNA single strand (dT)18 leads to electronically excited states that are potential gateways to DNA photolesions. Using time-resolved infrared spectroscopy we characterized a species with a lifetime of ∼100 ps and identified it as a charge separated excited state between two thymine bases.
