This review provides a comprehensive overview of the applications of helium nanodroplets
in the study of ensembles of atoms and molecules, ie clusters and complexes. These …

Helium droplets represent a cold inert matrix, free of walls with outstanding properties to
grow complexes and clusters at conditions that are perfect to simulate cold and dense …

Recent advances in laboratory spectroscopy lead to the claim of ionized
Buckminsterfullerene (C60+) as the carrier of two diffuse interstellar bands (DIBs) in the near …

In the present work we observe that helium nanodroplets colliding with surfaces can exhibit
splashing in a way that is analogous to classical liquids. We use transmission electron …

Aims. A high spectral resolution investigation of diffuse interstellar bands (DIBs) in the near-
infrared (YJ band) is conducted to test new methods, to confirm and improve existing …

Infrared and electronic spectra are indispensable for understanding the structural and
energetic properties of charged molecules and clusters in the gas phase. However, the …

This review summarizes experimental activities to study the structure of molecular ions via
He tagging. The method is based on the attachment of a weakly bound helium atom to a …

We report the first helium-tagged electronic spectra of cationic adamantane clusters, along
with its singly, doubly, and triply dehydrogenated analogues embedded in helium droplets …

The identification of the carriers of the diffuse interstellar bands (DIBs) remains to be
established, with the exception of five bands attributed to C, although it is generally agreed …

The helium-tagging technique was employed to record absorption spectra of cold
anthracene cations and protonated anthracene. The evaluation of the spectra of the …
