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 [similar]100 ps and identified it as a charge separated excited state between two thymine bases..
