This course covers vibrational and rotational spectra; electronic spectra and photoelectron spectroscopy; magnetism; electron spin and nuclear quadrupole resonance spectroscopy; nuclear magnetic resonance spectroscopy; other spectroscopic methods. This graduate level course offers an opportunity to learn spectroscopic methods through in-depth analyses of the types of radiation, structures of materials, and the interactions between radiation and matter. Spectroscopic methods and principles designed to analyze organic, inorganic, and nanoscale materials will be described. Group theory and symmetry will be used to categorize these geometric and electronic structures, and the interpretation of spectroscopic data (absorption and vibrational) will be presented in such a way so that the relationships between structure or symmetry and spectroscopic data are clearly revealed. Spectroscopic methods (NMR and EPR) that can reveal the electronic and magnetic properties of nuclei and electrons will also be covered.
