Hydrogen Network Dynamics and Conformational Changes in Molecular Solids

Dinamic reorganization of molecular conformation. and structural reorientation study, as well as hydrogen bonding rearrangement processes in molecular and polymeric systems.  The University of Coimbra was responsible for the evaluation and analysis of the properties of the studied systems (e.g. p-terfenil crystals and benzoic acid), through vibrational studies (Raman spectroscopy and infrared absorption) as a function of temperature.
