2. 1. Synthesis of complex organics via molecular growth mechanisms : Combined experimental and theoretical studies on ion-neutral reactions of C2H2N+ with ubiquitous hydrocarbons in Titan's ionosphere

   Author : Pantea Fathi; Wolf Geppert; Paul Scheier; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Astrochemistry; Complex molecules; Ion-neutral reactions; Mass spectrometry; Planetary and satellite atmospheres; Titan; kemisk fysik; Chemical Physics;

   Abstract : To provide insights on the molecular growth mechanisms leading to large carbon and nitrogen-bearing species in Titan’s ionosphere, laboratory measurements of ion-neutral reactions were conducted and the results are presented in the following doctoral dissertation. The product ions of the C2H2N+ reactions with saturated and unsaturated neutral hydrocarbons have been investigated using Guided Ion Beam Mass Spectrometer (GIB-MS). READ MORE

4. 2. Probing biomolecular fragmentation

   Author : Nicole Haag; Henrik Cederquist; Henning T. Schmidt; Paul Scheier; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; fysik; Physics;

   Abstract : This thesis deals with fragmentation of complex molecular ions, especially biomolecules, in gas phase collision experiments. The aim is to investigate the relations between energy deposition and fragmentation and to shed light on the mechanisms behind energy and charge transfer processes in collisions involving the building blocks of life.
