1. Theoretical studies of chemical dynamics on excited states, driven by non-adiabatic effects : Charge recombination reactions
Sammanfattning : This thesis is based on theoretical studies of molecular collisions occurring at relatively low to intermediate collision energies. The collisions are called dissociative recombination (DR) and mutual neutralization (MN). LÄS MER
2. A theoretical perspective on photoinduced reactions - based on quantum chemical models and non-adiabatic molecular dynamics
Sammanfattning : The broad range of applications for photochemical reactions is the result of light-matter interaction at the electronic level. The diverse application of photochemistry in various fields, including photovoltaic materials, molecular switches, and biological systems are due to electronic and structural transformations induced by photoexcitation as well as molecular alteration due to electron and charge transfer.

3. Molecular beam study of non-adiabatic electron transfer in the Cl2+Ksurf surface reaction
Sammanfattning : Halogen molecules impinging on alkali metal surfaces constitute model systems for studies of charge transfer, dissociation dynamics and non-adiabatic energy dissipation in molecule-surface reactions. This thesis reports emission of exo-electrons and photons from the surface as a result of strong non-adabaticity in the Cl2 gas on K$^{solid}$ reaction. LÄS MER
4. Photo-induced molecular processes and charge recombination reactions driven by non-adiabatic couplings
Sammanfattning : This thesis is based on a number of theoretical studies of molecular processes in which non-adiabatic effects play a crucial role. The main part is devoted to the photophysics and photochemistry of five-membered aromatic heterocyclic compounds, with particular focus on furan and thiophene. LÄS MER
5. Dynamics of Magnetic Molecules under Electrical Control
Sammanfattning : This thesis theoretically studies the dynamics of molecular magnets under electrical control. Molecular magnets are nanoscale magnets that can, e.g., consist of single-molecules or single-atoms. LÄS MER
