Photoelectron and infrared spectroscopy were applied to problems of molecular structure and reactivity and were studied as possible means of chemical analyses. The photoelectron spectra of a large number of molecules were measured in the 0-21 eV range. Ionization potentials were assigned in most cases to specific molecular orbitals. Shifts of particular energy levels in related series of molecules were interpreted in terms of inductive and conjugative effects. Some of the ionization potentials were correlated with variations in chemical reactivity. Infrared measurements in the 5000 - 10cm range were directed at systems involving hydrogen bonding in the gaseous phase with some studies of hydrogen bonding equilibria in an inert solvent. The use of the fine structure of vibration-rotation bands to determine molecular constants was considered. Author
