11. Cosmic Molecules and Clusters : Knockout Driven Reactions
Sammanfattning : Fullerenes and PAHs (polycyclic aromatic hydrocarbons) are two families of carbon based molecules. These are both present in the interstellar medium, and are there believed to play important roles in various processes, including the formation of stars in the case of PAHs. LÄS MER
12. Collision- and photon-induced dynamics of complex molecular ions in the gas phase
Sammanfattning : In this thesis, I report experiments probing collision- and photon-induced molecular dynamics in the gas phase. Excited molecules formed in such interactions may relax by emitting electrons or photons, isomerization or fragmentation. LÄS MER
13. The role of knockout driven fragmentation in collision with isolated complex molecular systems
Sammanfattning : This licentiate thesis covers results from collision induced dissociation (CID) experiments of Polycyclic Aromatic Hydrocarbons (PAHs), hydrogentated PAHs (HPAHs) and porphyrins. PAHs and HPAHs are believed to play key roles in the evolution of complex molecules in space, while porphyrins are essential for various functions in living organisms. LÄS MER
14. Anions from the lab to ionospheres
Sammanfattning : Anion processes have been in the focus of interest during the last decades, especially due to their importance in planetary ionospheres. Previous observations done by the Cassini Plasma Spectrometer, detected a multitude of heavy neutral and ionic molecules in the ionosphere of Saturn's moon Titan. LÄS MER
15. Mechanisms of Anion Reactions from the lab to ionospheres
Sammanfattning : A multitude of heavy neutral and ionic molecules have been discovered by the Cassini Plasma Spectrometer in the ionosphere of Saturn's largest moon Titan. However, only three cyano anions were explicitly identified there, namely CN-, C3N- and C5N-. LÄS MER
