1. Excited State Aromaticity and Antiaromaticity : Fundamental Studies and Applications
Abstract : The central theme of this thesis is the ability to tune various molecular properties by controlling and utilizing aromaticity and antiaromaticity in the lowest electronically excited states. This investigation is based on qualitative theory, quantum chemical (QC) calculations and experimental work. READ MORE

2. Ground and Excited State Aromaticity : Design Tools for π-Conjugated Functional Molecules and Materials
Abstract : The main focus of this thesis is on the aromaticity of the ground state and electronically excited states of π-conjugated molecules and polymers, as well as how aromaticity is connected to their properties.The electronic structures of polybenzenoid hydrocarbons (PBHs) were explored through density functional theory (DFT) calculations and the π-component of the electron localization function (ELFπ).

4. The short, excited life of tellurium : Lifetime analysis of excited states in the Te midshell region
Abstract : In this licentiate thesis, lifetimes of low lying excited states in the midshell region of tellurium isotopes are discussed. The nuclear lifetimes are interesting properties to study, since they are inversely proportional to the transition probabilities, which contain information on the underlying structure of the nucleus.

5. Tuning of the Excited State Properties of Ruthenium(II)-Polypyridyl Complexes
Abstract : Processes where a molecule absorbs visible light and then converts the solar energy into chemical energy are important in many biological systems, such as photosynthesis and also in many technical applications e.g. photovoltaics. READ MORE
