Abstract/Summary:
The focus of this thesis is on understanding the spectroscopic implications of excited electronic state interactions in metal containing and inorganic complexes. This thesis deals with many diverse topics of inorganic spectroscopy which include Herzberg-Teller vibronic coupling of electronic states, electronic effects in two-chromophore systems, the relationship between the excited state distortions of the initially populated state during photofragmentation and photolytically deposited thin films, and resonance Raman deenhancement. This thesis also introduces some preliminary results of some interesting luminescent compounds such as homoleptic metal-carbonyl and metal-dialkylamido complexes. Throughout the chapters of this thesis, the compounds are studied by absorption, luminescence, and Raman spectroscopies. These fundamental tools are used to investigate how the excited electronic states interact and how they influence the electronic and vibrational spectra. In chapter 3, higher energy multiphoton induced excited electronic states are studied by time of flight mass spectroscopy and pulsed laser photofragmentation. In chapters 1, 2, 4, and 6 the electronic spectra are theoretically interpreted through the time dependent point of view of electronic spectroscopy. The time dependent theory of electronic spectroscopy developed by Professor Eric Heller provides for a deeper understanding of excited state interactions in regards to inorganic spectroscopy. The overall emphasis of this thesis is not to focus on a small select part, but to expand the general knowledge of inorganic spectroscopy of metal-containing and inorganic complexes.
