Understanding the properties of electronically excited states is a challenging task that
becomes increasingly important for numerous applications in chemistry, molecular physics …

A detailed understanding of radiative and nonradiative processes in peptides containing an
aromatic chromophore requires the knowledge of the nature and energy level of low-lying …

In an effort to illuminate why nature has chosen a particular set of bio-molecular 'building-
blocks' for life, recent years have seen an up-surge of gas-phase spectroscopy experiments …

Molecular triplet states constitute a crucial gateway in the photochemical reactions of
organic molecules by serving as a reservoir for the excess electronic energy. Here, we …

By combining UV transient absorption spectroscopy with sub-30-fs temporal resolution and
CASPT2/MM calculations, we present a complete description of the primary photoinduced …

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

Time-resolved photoelectron imaging was used to investigate the dynamical evolution of the
initially prepared S 1 (ππ*) excited state of phenol (hydroxybenzene), catechol (1, 2 …

We demonstrate, for the first time, the application of rare-gas-filled hollow-core photonic
crystal fibers (HC-PCFs) as tunable ultraviolet light sources in femtosecond pump–probe …

The valence and core-level photoelectron spectra of gaseous indole, 2, 3-dihydro-7-
azaindole, and 3-formylindole have been investigated using VUV and soft X-ray radiation …

We present an overview of experimental and theoretical investigations exploring the
dynamical evolution of Rydberg-to-valence character in the electronically excited states of …
