1. Electronic Energy Transfer within Asymmetric Pairs of Fluorophores: Partial Donor-Donor Energy Migration (PDDEM)
Sammanfattning : A kinetic model of electronic energy migration within pairs of photophysically non-identical fluorophores has been developed. The model applies to fluorescent groups that exhibit different photophysical and spectral properties when attached to different positions in a macromolecule. LÄS MER
2. Extended Förster Theory of Electronic Energy Transport within Pairs of Reorienting Chromophoric Molecules
Sammanfattning : An extended Förster theory (EFT), previously derived (L. B.-Å. Johansson et al. LÄS MER
3. Fluorescence studies of complex systems : organisation of biomolecules
Sammanfattning : The homo and hetero dimerisation of two spectroscopically different chromophores were studied, namely: 4,4-difluoro-4-bora-3a,4a-diazas-indacene (g-BODIPY) and its 5-styryl-derivative (r-BODIPY). Various spectroscopic properties of the r-BODIPY in different common solvents were determined. LÄS MER
4. Two-Photon Excited Fluorescence Depolarisation : Experimental and Theoretical Development
Sammanfattning : We have studied fundamental aspects of time-resolved two-photon excited fluorescence depolarisation. The thesis presents experimental as well as theoretical progress. LÄS MER
5. On the quantitative analysis of electronic energy transfer/migration in proteins studied by fluorescence spectroscopy
Sammanfattning : Two recently developed theories of electronic energy transfer/migration were for the first time applied to real protein systems for extracting molecular distances. The partial donor-donor energy migration (PDDEM) is an extension to the previously developed donor-donor energy migration (DDEM, F Bergström et al PNAS 96, 1999, 12477) which allows using chemically identical but photophysically different fluorophores in energy migration experiments.
