  PIRENEA and PIRENEA 2 are experimental setups dedicated to the study of
fundamental molecular processes involving species of astrochemical interest.
The coupling of a VUV source to PIRENEA has allowed us to study the
fragmentation pathways and stability of polycyclic aromatic hydrocarbons (PAHs)
containing aliphatic bonds under conditions relevant for astrophysical
photodissociation regions. PIRE-NEA 2 will open the possibility to extend these
studies to larger systems such as PAH clusters, and more generally to study
gas-nanograin-photon interactions.
