Confinement

We study changes in order and dynamics of small molecules and polymers in nanopores with different spectroscopic approaches. By means of the recently developed "Transition Moment Orientational Analysis", an ellipsometric technique based on IR spectroscopy, the 3D orientational order in pores is measured. We also study dynamics with Dielectric Spectroscopy and conformational changes with IR and Raman Spectroscopy.
