>> The chain of chemical reactions leading towards life is thought to begin in molecular clouds when carbon atoms are fixed into molecules, initiating the synthesis of complex organic species. Up to 20 % of the cosmic carbon is believed to be in the form of Polycyclic Aromatic Hydrocarbons. Anions also play crucial roles in a range of astrophysical environments and planetary atmospheres. How large molecules and anions can survive and evolve in harsh environments, such as in planetary nebulae with strong UV radiation fields or in shock-heated outflows of supernovae is still not fully understood. Spectroscopic observations, combined with sophisticated astrochemical models to interpret the collected spectra, provide much of our knowledge of these processes. However, few reactions have been studied experimentally in a range of collision energies relevant for cold astrophysical environments. Uncertainties in the underlying chemical data in these models limit our understanding of the molecular universe.
>> In this talk, I will present some key reactions for the abundances of chemical compounds and the ionization balance in various astrophysical environments, and show results of experiments performed at DESIREE facility in Stockholm University and elsewhere to address some of these issues. Several methods used in these experiments will be briefly presented including the merged beams method and collision induced dissociation. Our reaction studies will help to provide a better basis for astrochemical models and benchmarks for future theoretical development.
