1. Excited States of Carotenoids and Their Functions in Light Harvesting
Abstract : The research presented in this thesis is focused on characterization of photophysical properties of lowest singlet excited states of carotenoids and their functions in the process of photosynthetic light harvesting. It is shown that the various light-harvesting complexes utilize different strategies to achieve efficient energy transfer from carotenoids to (bacterio)chlorophylls. READ MORE

2. Excited States in Negative Ions
Abstract : This thesis covers experimental studies of atomic negative ions with the main goal of increasing our fundamental understanding of these fragile quantum systems. Comparisons of measurements and calculations have been used to increase our understanding of these highly correlated, yet simple, systems. READ MORE

3. Reaction dynamics on highly excited states
Abstract : In this thesis I have performed theoretical studies on the reaction dynamics in few-atom molecules. In particular, I have looked at reaction processes in which highly excited resonant states are involved. READ MORE

4. The Fate of Electronically Excited States : Ultrafast Electron and Energy Transfer in Solvated Donor-Acceptor Systems
Abstract : Processes where a molecule absorbs visible light and then disposes of the excess energy via electron/energy transfer reactions have an important role both in nature (e.g. in photosynthesis) and in many technical applications (e.g. READ MORE

5. Theoretical Studies on Kinetics of Molecular Excited States
Abstract : HTML clipboardKinetics on molecular excited states is a challenging subject in the field of theoretical chemistry. This thesis pays attention to theoretical studies on kinetics of photo-induced processes, including photo-chemical reactions, radiative and non-radiative transitions (intersystem crossing and internal conversion) in molecular and bio-related systems.
