title: Identification of charge separated states in thymine single strands.
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.
