  4. 3. Molecular Insight into Ion-Specific Interactions : Vibrational Sum Frequency Study of the Carboxylic Acid Moiety

    Författare :Adrien Sthoer; Eric Tyrode; Paul Cremer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; specific ion effects; carboxylic acid; fatty acid Langmuir monolayer; vibrational sum frequency spectroscopy; VSFS; Electrical double layer;

    Sammanfattning : Ion specific effects at charged interfaces find numerous applications in colloidal sciences and play a vital role in many biological processes. Despite having been studied for over a century, starting with the work of F. Hofmeister in the 1880s, a comprehensive molecular  understanding remains elusive. LÄS MER

  5. 4. Electronic and Vibrational Coherence in Photosynthetic and Model Systems

    Författare :Mirianas Chachisvilis; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Ultrafast relaxation; Porphyrins; Delocalization; Anisotropy; Wavepacket; Vibrational Coherence; Excitons; Electronic coherence; Energy transfer; Femtosecond spectroscopy; Photosynthesis;

    Sammanfattning : Ultrafast optical response and excitation energy dynamics in light harvesting pigment-protein complexes and in a few model systems have been studied both experimentally and theoretically. Femtosecond light pulses were employed to excite the system and monitor the subsequent time evolution of the transient absorption kinetics and anisotropy. LÄS MER

  7. 5. Surface Vibrational and Electron Spectroscopy - Experiments and first-principle calculations

    Författare :Martin Andersson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gränsskikt; anharmonicity; Ytkemi; Surface and boundary layery chemistry; adsorbates; metal surface; density functional theory; first-principle calculations; electron spectroscopy; reflection-absorption infrared spectroscopy; vibrational spectroscpy;

    Sammanfattning : This work deals with interpretation of experimental surface spectroscopic data with the aid of first-principle calculations. Surface infrared reflection-absorption spectra as well as spectra from the electron spectroscopic methods photoemission and X-ray absorption are considered. LÄS MER
