  2. 1. Excited States of Carotenoids and Their Functions in Light Harvesting

    Author : Donatas Zigmantas; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spektroskopi; magnetic and optical properties; Carotenoids; light-harvesting; excited states; excitation energy transfer; femtosecond spectroscopy; supraconductors; magnetic resonance; electrical; Condensed matter:electronic structure; time-resolved fluorescence spectroscopy; magnetisk resonans; supraledare; magnetiska och optiska ; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; relaxation; spectroscopy;

    Abstract : The research presented in this thesis is focused on characterization of photophysical properties of lowest singlet excited states of carotenoids and their functions in the process of photosynthetic light harvesting. It is shown that the various light-harvesting complexes utilize different strategies to achieve efficient energy transfer from carotenoids to (bacterio)chlorophylls. READ MORE

  4. 2. High-resolution measurement of the ¹⁶O(γ,pn) reaction

    Author : Lennart Isaksson; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pn ; E_gamma = 67-76 MeV; resolved states; cross-sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:1996:Isaksson; 16O gamma; Photonuclear reaction;

    Abstract : The 16O(gamma,pn) reaction has been measured with a resolution high enough to resolve individual low-lying states in the residual 14N nucleus. The relative population of the states provides detailed information about the quantum numbers of the proton-neutron pairs on which photons are absorbed. READ MORE

  5. 3. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin

    Author : Robert Bosman; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rhodopsin; SRII; SRII-HtrII; Time-resolved crystallography; Time-resolved wide angle x-ray scattering; TR-X; TR-WAXS; Serial crystallography;

    Abstract : Responding to different light conditions is an essential process for many organisms on earth. Unicellular organisms are no exception to this and mechanisms for controlling cellular movement must often be sensitive to light. READ MORE
