We investigate attachment of slow electrons (0-10 eV) to naphthalene (Np) clusters in a crossed beam experiment. Supersonic expansions under different conditions using different buffer gases generate the clusters: in He, Ne, and low pressure Ar, neat (Np)N clusters are formed, while we also observe mixed clusters of naphthalene with rare-gas atoms in co-expansion with Ar above 0.5 bar and with Kr.

To uncover details about the composition of neutral clusters, we aim to elucidate the ion formation processes in FA ⋅ W clusters initiated by interaction with electrons and determine the extent of cluster fragmentation.

- Trifluoroacetyl chloride (CFCOCl) is produced in the atmosphere from the breakdown of hydrochlorofluorocarbons and can generate reactive halogen radicals.
- This study investigates how CFCOCl molecules and their clusters react when exposed to electron ionization and attachment using a combination of experiments and quantum chemical calculations.
- The findings reveal that ionization leads to significant fragmentation, with specific bond dissociations producing various ions, and that electron attachment causes different reactions depending on the energy levels, which could have implications for atmospheric chemistry.
We investigated the dissociation of nitric acid on large water clusters (HO), ≈ 30-500, , ice nanoparticles with diameters of 1-3 nm, in a molecular beam. The (HO) clusters were doped with single HNO molecules in a pickup cell and probed by mass spectrometry after a low-energy (1.5-15 eV) electron attachment.
