Funding: 3200000 SEK


With this starting grant, I propose to build up new instrumentation to study the intrinsic electronic properties and photoprocessing of cryogenically cooled, gas-phase molecular ions. I will use a combination of optical spectroscopy and mass spectrome called action spectroscopy. My research will focus on molecules important in the contexts of biophysics (e.g. DNA and nucleotides) and astrophysics (e.g. Polycyclic Aromatic Hydrocarbons and fullerenes). The experiments I have proposed will impact our understanding of avian navigation, and the chemical makeup of the interstellar medium. I will make use of the facilities and equipment available to the Atomic Physics group at Stockholm University, in particular the Double ElectroStatic Ion Ring ExpEriments (DESIREE) infrastructure and Electrospray Ion Source Lab (EISLAB). I will bring to the group new expertise in the specialized techniques of action spectroscopy, and lead the implementation of these techniques at SU, including the modification of existing apparatus. I will also expand the experimental capabilities of the group in a completely new direction by developing a unique new instrument for measuring fluorescent light emission from cold, gas-phase ions. These new tools which I will develop will be used for a variety of research projects by me and by other users of the group's facilities, including international collaborators.
