1. Structure-Function Relationships in RuII Complexes with Unconventional Ligands: Photophysical and Photochemical Studies
Abstract : The rich photophysics, photochemistry and electrochemistry of RuII complexes have attracted intense research interest in widely disparate fields. A large portion of the studied and applied complexes are derived from the archetypical [Ru(bpy)3]2+ (bpy is 2,2’-bipyridine), which absorbs in the visible region, displays a long lived (~1 μs), emissive metal-to-ligand charge transfer state, and shows reversible electrochemistry in both the ground and excited state.

2. An Ultrafast Spectroscopic and Quantum-Chemical Study of the Photochemistry of Bilirubin : Initial Processes in the Phototherapy for Neonatal Jaundice
Abstract : Bilirubin is a degradation product of haem, which is constantly formed in allmammals. Increased levels of bilirubin in humans lead to jaundice, a conditionthat is very common during the first days after birth. This neonataljaundice can routinely be treated by phototherapy without any serious sideeffects. READ MORE

3. Theoretical Studies on Magnetic and Photochemical Properties of Organic Molecules
Abstract : The present thesis is concerned with the theoretical studies on magnetic and photochemical properties of organic molecules. The ab initio and first principles theories were employed to investigate the vibrational effects on the isotropic hyperfine coupling constant (HFCC) known as the critical parameter in electron paramagnetic resonance spectrum, the theoretical simulations of the vibronically resolved molecular spectra, the photo-induced reaction mechanism of α-santonin and the spin-forbidden reaction of triplet-state dioxygen with cofactor-free enzyme.

4. Light-Induced Routes to Sustainable Biocrudes for Fuels and Lubricant Oils
Abstract : Fossil-based hydrocarbons are at present the ideal compounds for jet fuels and lubricant oils, so their replacement by novel technologies is not easy. Instead, sustainable routes to hydrocarbons, such as sunlight-driven processes, are desired to reduce the environmental impact by the transport sector. READ MORE

5. Water at surfaces and interfaces from first-principles studies
Abstract : Water is ubiquitous in nature and ordinary to us. However, no matter how common it is, water is unique, mysterious, and has numerous unusual properties, many of which still lack a scientific interpretation. READ MORE
