Recent progress in both data quality and theoretical models has led to a renaissance of detailed vibrational analyses in many areas of inorganic and materials chemistry. Examples of structural effects (cis/trans-isomers) and phase transitions driven by electronic structure will be discussed. Luminescence spectroscopy reveals excited-state characteristics in addition to the ground-state effects probed by vibrational spectra. Complexes with d3 electron configuration show surprising wavelength variations depending on the nature of the metal center. In addition, variations of luminescence spectra at variable temperature and pressure reveal the influence of intermolecular effects on luminescence properties.
