Welcome to the Nonlinear Interfacial Spectroscopy Group

Our group focusses on the investigation molecular structures and dynamics at interfaces using ultrafast nonlinear spectroscopic techniques. Our goal is to better understand the unique physical properties of molecular interfaces and unravel the mechanisms of interfacial physico-chemical processes.

We therefore employ and develop novel spectroscopic tools based on second order nonlinear light-matter interactions where we combine vibrational information with spatial resolution. This includes phase-sensitive SFG/DFG spectroscopy and microscopy as well as time-resolved techniques such as vibrational pump-probe and multidimensional spectroscopies.

Latest news:

The work by Alex and Ben on phase-resolved SFG microscopy is now published in Nature Communications. This work uncovers the details of the molecular structures in phospholipid model membranes showing fascinating hierarchical molecular packing motifs with spiralling molecular directions. It is also our first direct observation of molecular in-plane order in a monolayer.
