The photophysics and photochemistry of DNA is of great importance due to the potential
damage of the genetic code by UV light. Quantum mechanical studies have played a key …

Gas-phase spectroscopy lends itself ideally to the study of isolated molecules and provides
important data for comparison with theory. In recent years, we have seen enormous …

Understanding the energy it takes to build or break chemical bonds is essential for scientists
and engineers in a wide range of innovative fields, including catalysis, nanomaterials …

Biochemical reactions are subject to the particular environmental conditions of planet earth,
including solar irradiation. How DNA responds to radiation is relevant to human health …

The mechanisms that are responsible for the rapid deactivation of the 1nπ* and 1ππ*
excited singlet states of the 9H isomer of adenine have been investigated with …

Numerous post-transcriptional modifications of transfer RNAs have vital roles in translation.
The 2-methylthio-N 6-isopentenyladenosine (ms2i6A) modification occurs at position 37 …

The UV chromophores in DNA are the nucleic bases themselves, and it is their photophysics
and photochemistry that govern the intrinsic photostability of DNA. Because stability is …

In this paper we simulate the deactivation dynamics of photoexcited 6-thioguanine, a
cytotoxic analogue of the canonical DNA/RNA base guanine, using a direct surface hopping …

By employing broadband femtosecond Kerr-gated time-resolved fluorescence (KTRF) and
transient absorption (TA) techniques, we report the first (to our knowledge) femtosecond …
