  2. 1. Association and Interactions in Protein-Surfactant Systems

    Author : Anna Stenstam; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catanionic surfactant; SANS; NMR; gel; sodium alkylsulfate; Protein-surfactant interactions; lysozyme; LH2; Physical chemistry; Fysikalisk kemi;

    Abstract : Aggregation in protein-surfactant systems have been studied with the ambition of reaching a deeper understanding of the balance of the interaction forces involved. A pure system with maximized electrostatic interactions has been used. READ MORE

  4. 2. Coherent Multidimensional Spectroscopy: Development of Efficient Data Acquisition and Analyses of Quantum Dot 2D Spectra

    Author : Zhengjun Wang; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent Multidimensional Spectroscopy; quantum beating; quantum coherence; 2D electronic spectroscopy; 2D fluorescence spectroscopy; Compressed Sensing theory; CdSe QDs; LH2;

    Abstract : Coherent multidimensional spectroscopy (CMDS) is the most complete nonlinear optical technique based on the interaction of multiple short laser pulses with matter. It has grown to play a significant role in studies of optoelectronic materials and pigment protein complexes. READ MORE

  5. 3. Multidimensional Fluorescence Polarization Imaging of Single Light Harvesting Complexes

    Author : Sumera Tubasum; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Light Harvesting Complexes; Single Molecule Spectroscopy; Polarization Spectroscopy; Exciton Dynamics; Spectral Disorder;

    Abstract : This thesis presents my research journey in the Department of Chemical Physics,Lund University. Multidimensional fluorescence polarization imaging is used to study single LH2s. The method uses linearly polarized excitation light and the emission is detected through a polarizer. READ MORE

  6. 4. Energy Transfer Patterns in Photosynthetic Antenna System of Purple Bacteria

    Author : Susan Hess; Kemisk fysik; []

    Abstract : Steady state and time-resolved absorption and fluorescence spectroscopy have been used to investigated the energy transfer in photosynthetic purple bacteria. Picosecond light pulses were used in measurements of Rb. READ MORE

  7. 5. Ultrafast Dynamics in Ground and Excited States of Porphyrin Molecules

    Author : Peter Martinsson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intra- and intermolecular dynamics.; Zn-porphyrin; bacteriochlorophyll a; chlorophyll b; Femtosecond transient absorption spectroscopy; chlorophyll a; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis describes inter and intramolecular dynamics in porphyrin molecules. To create a basis for understanding the energy and electron transfer processes in photosynthesis, the ultrafast dynamics of monomeric chlorophyll a, chlorophyll b and bacteriochlorophyll a were studied with ultrashort laser pulses.
