Raman spectroscopy for investigating mass transport and concentration gradients in mixtures (A07)

• Subject Area: Synthesis and Properties of Functional Materials ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 265191195

A07 aims at resolving concentration gradients by Raman spectroscopy in order to better understand mixture-specific processes during dewetting and wetting and to provide corresponding data for model development and simulation. The Raman stable isotope imaging method will be further developed in order to establish it as an imaging concentration measurement method for binary mixtures. Aims are the assignment of Raman bands, the determination of physicochemical parameters for deuterated fluids and the determina-tion of the possibilities and limits of the method. The concentration profiles will be used to describe the mass transport processes in binary mixtures near the contact line.
