Sequential attachment of atomic hydrogen to polycyclic aromatic hydrocarbon (PAH) molecules such as coronene leads to a gradual transition from an aromatic to an aliphatic molecular electronic structure. At the same time, the planar PAH geometry breaks down and is gradually replaced by a corrugated structure. The process is very similar to hydrogenation of graphene sheets, which can be employed to open up the graphene band gap in a controlled way. Furthermore, interactions of atomic hydrogen with PAHs are considered relevant for formation H2 formation in the interstellar medium.

In a collaboration between theory (M. Rapacioli and Aude Simon, Toulouse, France), astronomy ( S. Cazaux , Delft) and experiment (N. Foley, R. Hoekstra, T. Schlathölter, ZIAM) this hydrogenation process for the model PAH cation coronene was thoroughly studied. The study established how the balance between energy deposition by hydrogen attachment and the extent of cooling between subsequent attachment events manifests in mass spectra dominated by small hydrocarbon fragment cation and multiply hydrogenated coronene cations.
