- Development of ab initio quantum chemical methods, in particular, mul tireference configuration interaction.
- Theoretical description of electronically excited states, molecular s pectra and photochemistry, including coupling of electronic and nuclear motion (non-adiabatic effects), s pin-orbit effects and non-radiative processes.
- Atmospheric molecules and ions, their lifetimes in excited states and decomposition due to radiative and non-radiative processes.
- Stability and building principles of small clusters.
