Advanced Techniques in Infrared Spectroscopy 1200-3MON14Z

During the lecture, various experimental techniques are discussed that enable investigations of standard and non-standard samples. The includes techniques like: PMIRRAS - polarization modulation infrared reflection-absorption spectroscopy, ATR - attenuated total internal reflection, infrared microscopy and imaging, 2D-IR two-dimensional infrared spectroscopy and transmission measurements for samples in different states of focus with middle, far and near infrared regions. Further, selected methods of mixture analysis and chemometric methods are also discussed - principal component analysis. Each experimental technique is discussed along with the basic theoretical background necessary for the proper planning of the experiment and the interpretation of the results. Example applications for presented techniques are shown. The lecture covers intermolecular interactions that affect the spectra (hydrogen bonds, interaction of the adsorbate with the surface), studies of the arrangement of molecules in layers and crystals. Exemplary spectra of carbon materials, polymers and tissues are discussed. The examples come from the scientific literature of the last few years.
