1. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics
Sammanfattning : Dissociation dynamics of the ionized molecules HCl and the deuterated system DCl has been studied in gas-phase using synchrotron based photoelectron spectroscopy (PES).The inner-valence "(4σ)-1" photoionization band for DCl and HCl was recorded using maximum resolution in order to probe an interference pattern between a dissociative and a bound electronic state.

2. Development and Implementation of Methods in Theoretical Chemistry
Sammanfattning : The method development research in the field of theoretical chemistry is the never ending quest for methods that are faster, gives more accurate results, and expands the possibilities. The work in this thesis is no exception to that statement. LÄS MER
3. Ultrafast Photo-induced Reaction Dynamics of Small Molecules
Sammanfattning : The main focus of this thesis is the investigation of the dissociation dynamics of aryl halides using femtosecond pump-probe spectroscopy. In the monohalogenated aryl halides, iodo-, bromo- and chlorobenzene, the rate of dissociation following excitation at 266 nm in the gas phase increased with increasing mass of the halogen atom.

4. Femtosecond Dynamics of Dissociation and Isomerization Reactions in Solutions
Sammanfattning : The main purpose of this work has been to investigate the fundamental dynamics of photodissociation and photo-induced isomerization reactions in the condensed phase. These "elementary" reactions have been chosen as model processes for exploring the influence of the solvent on a chemical event, as well as the factors that control this influence. LÄS MER
5. Theoretical Studies on the Molecular Mechanisms of Photo-Catalytic Reactions on TiO2 Surfaces
Sammanfattning : Photocatalysis is a promising technology that can effectively convert the solar energyinto sustainable green energy. However, theoretical studies on the molecular mechanisms of photocatalytic reactions are rare. LÄS MER
