Vibrational Spectroscopy in Polymer Science

Vibrational spectroscopy provides information on macromolecules with respect to their composition, structure, conformations, and intra- and intermolecular interactions. Vibrations of molecules consist of periodic changes of the length of bonds between atoms and of the bond angles. Vibrational modes of molecules exhibit discrete values of energy. Due to interaction of electromagnetic radiation with the studied substances we obtain vibrational spectra providing information on the molecular structure. While infrared spectroscopy employs absorption of infrared radiation, Raman spectroscopy is based on inelastic scattering of monochromatic light, usually from a laser emitting in the visible or near-infrared region. Both methods are widely used in polymer science.

Current Research Topics

The activity of the Department of Vibrational Spectroscopy is focused on the structure analysis of macromolecules, on the study of interactions in polymer solutions and blends, and on the study of molecular structure of conducting polymers which includes understanding the interaction of electromagnetic radiation with free-charge carriers in conducting polymers structure. Information about molecular structure of the systems obtained from infrared and Raman spectra are correlated with macroscopic properties of the materials. Modern instrumental equipment provides the possibility of analysis of a wide range of samples, from low-molecular-weight compounds and polymers in solution to solid materials in many forms (films, gels, layers, powders, composites, etc.), by advanced spectroscopic methods.
