Electronic structure of pyrimidine bases — •Thomas Schultz1, Kyriaki Kosma2, Christian Schröter1, and Hans-Herrman Ritze1 — 1Max Born Institut, Max-Born Strasse 2A, 12555 Berlin — 2FORTH, P.O. Box 1527, 71110 Heraklion, Greece
The electronic structure and photochemical behavior of the DNA bases is topic of dozens of theoretical and experimental studies every year. Despite these efforts, there is no consensus about the electronic properties of the pyrimidine bases. We performed time-resolved photoelectron and mass spectroscopy to assign the electronic states involved in the excited state relaxation of thymine and cytosine. Through a comparison with theoretical work, we hope to establish whether state-of-the-art calculations are capable to predict the correct excited state properties.
