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:

This work by Alex and Ben is now published in JPC Letters. The paper demonstrates the succsessful determination of the full 3D molecular orientation in phpospholipid monolayers by applying phase-resolved SFG microsocpy as function of sample rotation.

This work by Alex, Alvaro, and Vasilis is now published in Langmuir. It detemines the length scale of the structural anisotropy decay at the air-water interface using our depth-resolved SFG/DFG spectroscopy. This work is the first direct experimental measurement thickness of the interfacial water layer.
