  2. 1. An Infrared Study of Intermolecular Interactions in Gaseous Hydrogen Bonded Molecular Complexes

    Author : René Wugt Larsen; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intermolecular potential energy surface; Physical chemistry; Fysikalisk kemi; synchrotron radiation; infrared absorption spectroscopy; intermolecular vibration; molecular complex; Intermolecular interactions; hydrogen bond;

    Abstract : Intermolecular interactions are responsible for the deviations of gases from ideality, determine the three- dimensional structure and folding dynamics of biological molecules, and the binding of molecules to surfaces as in heterogeneous catalysis. The hydrogen bond is the most important intermolecular interaction. READ MORE

  4. 2. Resonant Soft X-ray Spectroscopic Studies of C60 and Related Materials

    Author : Tanel Käämbre; Arne Rosén; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : This thesis addresses the electronic structure of molecular and correlated solids using resonant inelastic soft X-ray scattering (RIXS), non-resonant X-ray emission, photoemissionand X-ray absorption spectroscopies. The use of monochromatised synchrotron radiation and improved energy resolution for X-ray emission have made it possible to elucidate the normal state transport properties and to get further insight into the electron-vibration coupling in fullerenes and the related compounds.

  5. 3. Far-infrared conformer-specific signatures of small aromatic molecules of biological importance

    Author : Vasyl Yatsyna; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Our understanding of many biological processes requires knowledge about biomolecular structure and weak intra- and intermolecular interactions (e.g. hydrogen bonding). Both molecular structure and weak interactions can be directly studied by far-infrared (or THz) spectroscopy, which probes low-frequency molecular vibrations. READ MORE

  6. 4. Characterization of Ultrashort Pulses And Ultrafast Dynamics of Molecules In the Liquid Phase

    Author : Ming Liu; KTH; []
    Keywords : Ultrafast Spectrascopy;

    Abstract : This thesis reports an alternative method for fully acomplete characterization of the UV pump pulse and white lightcontinuum probe pulse, which is commonly used in the pump-probeexperiments to investigate the ultrafast dynamics of molecules.Besides that, real dynamics of infrared cyanine dye molecules(Methyl-DOTCI) and photo-induced dissociation of trihalide ions(I3-or I2Br-) solvated in different organic solvent has alsobeen carefully investigated.
