Evolution has ensured that plants and animals have developed effective protection
mechanisms against the potentially harmful effects of incident ultraviolet radiation (UVR) …

We summarize how gas-phase ultrafast charged-particle spectroscopy has been used to
provide an understanding of the photophysics of DNA building blocks. We focus on adenine …

The availability of non-radiative decay mechanisms by which photoexcited molecules can
revert to their ground electronic state, without experiencing potentially deleterious chemical …

Here we refine and assess two computational procedures aimed to include the effect of
thermal fluctuations on the electronic spectra and the ultrafast excited state dynamics of …

Novel experimental techniques and computational methods have provided new insight into
the behavior of reactive intermediates in solution. The results of these studies show that …

We introduce a method (FrD-LVC) based on a fragment diabatization (FrD) for the
parametrization of a linear vibronic coupling (LVC) model suitable for studying the …

The Watson–Crick A· T and G· C base pairs are not only electronically complementary, but
also photochemically complementary. Upon UV irradiation, DNA base pairs undergo …

If a molecular dication is produced on a repulsive potential energy surface (PES), it normally
dissociates. Before that, however, ultrafast nuclear dynamics can change the PES and …

The origin of life on Earth is one of the most fascinating questions of contemporary science.
Extensive research in the past decades furnished diverse experimental proposals for the …

The dynamics of chemical reactions in liquid solutions are now amenable to direct study
using ultrafast laser spectroscopy techniques and advances in computer simulation …
