The role of the UNITN node (at the Department of Physics, University of Trento) in the project is to study experimentally the reactivity of charged species (cations but also anions) under conditions (with regards to pressure and collision energy) as close as possible to those relevant in the interstellar medium. Daniela Ascenzi, from the Atomic and Molecular Physics Laboratory (https://molecular.physics.unitn.it/) has a well-established expertise in the investigation of the kinetics and dynamics of molecular systems. The activity is carried out exploiting 2D-trapping of ions using RF octupolar fields. The experimental set-up uses tandem guided ion beam mass spectrometry to measure absolute cross sections and product branching ratios as a function of collision energy for a variety of ion-molecule reaction systems in the gas phase under single collision conditions. In addition, the UNITN team has access to synchrotron radiation methods for the generation of energy/isomer selected ions via VUV photoionization and dissociative photoionization of appropriate precursors. The Laboratory of Bioorganic Chemistry (https://www.physics.unitn.it/89/chimica-bioorganica) lead by Ines Mancini has a profound know-how in chemical synthesis that is pivotal for the productions of non-commercially available precursors for the generation of radicals and ions to be used in reactivity studies.
