Spectroscopy
A special emphasis is put on theoretical spectroscopy in our group. The calculation and analysis of electronic and vibrational spectra by static and dynamic methods using e.g. perturbation theory, realtime propagation, and subsystem DFT are some of the research directions we have been following. In recent years, we have especially been interested in modelling of spectra for condensed phase systems. Besides studies for the inclusion of solvent effects in static calculations, we have focused on ab initio molecular dynamics as a tool to describe condensed phase systems and their dynamics at ambient conditions. Apart from the use of density functional theory embedding, we have, for instance, presented efficient computational approaches for Raman (optical activity) and sum frequency generation. Other directions have concerned efficient calculation of entire excitation profiles and off, near and onresonance spectra as well as spectroscopic signatures for chiral systems such as electronic circular dichroism.
