DNA monomers


We study the excited state relaxation of the DNA/RNA building blocks (bases, nucleosides, nucleotides) and their fluorescent analogs. We strive for a better insight in the very efficient internal conversion occurring after UV excitation and its dependence on the molecular structure and the solvent.

In general, the excited state lifetimes of these monomeric chromophores are so short that ultrafast techniques are needed. We use in particular femtosecond UV fluorescence spectroscopy.
