Welcome to the Multidimensional Molecular Spectroscopy (MuMoS) group! Our research focuses on ultrafast processes in solution. The systems we are interested in range from simple monomeric dye-molecules to protein-bound natural light harvesting complexes.

Based on home-built laser technology, we use visible and near-infrared laser pulses to excite valence electrons and nuclear motions in molecules or molecular aggregates. The ultrashort duration of sub-ten femtoseconds (10-15 seconds) of our laser pulses allows us to investigate coupling between electronic states as well as vibrational dynamics in large molecules or aggregates. The interplay between these degrees of freedom, vibrational and electronic, is crucial for the initial steps of photosynthetic processes and their remarkably high efficiency. We use two-dimensional electronic spectroscopy (2D-ES) and related techniques to investigate these fascinating phenomena.
