Rotationally inelastic scattering of cyanocyclopentadiene by helium atoms
Karina Sogomonyan, Malek Ben Khalifa, Phoebe Pierré +1
In the interstellar medium (ISM), polycylic aromatic hydrocarbons (PAHs) are believed to be an important carbon reservoir, accounting for up to a quarter of all interstellar carbon…

Chemistry and ro-vibrational excitation of HeH in the Planetary Nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
HeH belongs to the class of "reactive" ions that can be destroyed so quickly that chemical formation and destruction rates may compete with inelastic rates and should be consid…

Rotational Excitation of Vinyl Cyanide by Collisions with Helium Atoms at Low Temperature
Karina Sogomonyan, Malek Ben Khalifa, Jérôme Loreau
Among the numerous molecular systems found in the interstellar medium (ISM), vinyl cyanide is the first identified olephinic nitrile. While it has been observed in various sources,…
