1. Simulation of Relaxation Processes in Fluorescence, EPR and NMR Spectroscopy
Sammanfattning : Relaxation models are developed using numerical solutions of the Stochastic Liouville Equation of motion. Simplified descriptions such as the stochastic master equation is described in the context of fluorescence depolarisation experiments. Redfield theory is used in order to describe NMR relaxation in bicontinuous phases. LÄS MER
2. Theoretical studies of EPR parameters of spin-labels incomplex environments
Sammanfattning : This thesis encloses quantum chemical calculations performed in the framework of density functional response theory for evaluating electron paramagnetic resonance (EPR) spin Hamiltonian parameters of various spin-labels in different environments. These parameters are the well known electronic g-tensor and the nitrogen hyperfine coupling constants, which are extensively explored in this work for various systems. LÄS MER
3. Density Functional Theory for EPR and NMR Spin Hamiltonian Parameters
Sammanfattning : .... LÄS MER
4. EPR Studies of Ruthenium-Manganese Complexes as Biomimetic Models for Photosystem II - Approaching Artificial Photosynthesis
Sammanfattning : In natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. LÄS MER
5. The Oxygen Evolving cycle in Photosystem II studied with EPR Spectroscopy at different pH and Temperature
Sammanfattning : PSII catalyses the light-induced water splitting process which leads to electron transfer through the thylakoid membrane and formation of energy rich molecules. Several redox components including a Mn4Ca, an amino acid residueYZ, two special Chl molecules P680, two Pheo and two quinone molecules participate in this process. LÄS MER
