UVB–UVA region. The mechanistic study combining photochemical and photobiological techniques shows that irradiation of 5-formyluracil leads to a triplet excited state capable of sensitizingformation of cyclobutane pyrimidine dimers in DNA via a triplet–triplet energy transfer. This demonstrates for the first time that oxidatively generated DNA damage can behave as an intrinsic sensitizer and result in an
