Small carbocations are of longstanding interest in mass spectrometry, organic chemistry and
astrophysics, but there are few measurements of their spectroscopy in the gas phase. Of …

The optical absorption properties of (poly) aromatic hydrocarbons occluded in a nanoporous
environment were investigated by theoretical and experimental methods. The carbonaceous …

While action spectroscopy of cold molecular ions is a well-established technique to provide
vibrationally resolved absorption features, fluorescence experiments are still challenging …

The very fast relaxation of the excited states to the ground state in DNA/RNA bases is a
necessary process to ensure the photostability of DNA and its rate is highly sensitive to the …

The electronic spectroscopy of cold protonated indole was investigated experimentally and
theoretically. Two isomers were observed by experiment: The first isomer corresponds to the …

Protonated mixed pyrene–water clusters,(Py) m (H2O) nH+, where m=[1–3] and n=[1–10],
are generated using a cryogenic molecular cluster source. Subsequently, the mass-selected …

Excitation spectra of protonated and deuteronated anthracene are obtained by triple-
resonance dissociation spectroscopy. Very cold cations, protonated/deuteronated …

The halochromism in solution of a prototypical example of an azo dye, ethyl orange, was
investigated by using a combined theoretical and experimental approach. Experimental …

Solvation-dependent intracluster proton transfer (ICPT) within bare and Ar-tagged
protonated naphthalene–(water) n clusters, H+ (Np–W n) with n≤ 3, is characterized by …

The conformer-selected ultraviolet (UV) and infrared (IR) spectra of protonated
noradrenaline were measured using an electrospray/cryogenic ion trap technique combined …
