| dc.description.abstract | To better understand the link between light absorption and deleterious DNA photoproducts, the photophysics of DNA bases was investigate with femtosecond mid-IR transient absorption spectroscopy. Markers band for two excited states, a dark singlet state and a triplet state, were found. These marker bands provide insight into the nature and dynamics of the states. The results confirm a model for pyrimidine bases previous proposed based on UV-visible transient absorption measurements. This study provides an important foundation for future investigations of the role of these states in DNA. | en_US |
