1. An Infrared Study of Intermolecular Interactions in Gaseous Hydrogen Bonded Molecular Complexes
Sammanfattning : 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. LÄS MER
2. Resonant Soft X-ray Spectroscopic Studies of C60 and Related Materials
Sammanfattning : 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.

3. Far-infrared conformer-specific signatures of small aromatic molecules of biological importance
Sammanfattning : 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. LÄS MER
4. Characterization of Ultrashort Pulses And Ultrafast Dynamics of Molecules In the Liquid Phase
Sammanfattning : 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.
