Abstract Details

2016, Doctor of Philosophy, Miami University, Chemistry and Biochemistry.
In an extension of previous research by the Tierney group, a series of cobalt(II) ß-diketonates with clear dynamics was found in the literature for further spectroscopic studies. There are two chapters of studies on these complexes. Chapters 2 and 3 consist of nuclear magnetic resonance relaxation (NMR) studies. Chapter 2 focuses on the two complexes in the series with a bidentate amine ligand. Chapter 3 focuses on the three complexes in the series with monodentate amine ligands. The relaxation times were measured at magnetic fields of 4.7 and 7.0 T on the 19F nuclei of all five complexes and for 1H on two complexes. From these relaxation times, the electronic correlation times were extracted using a modified version of the Solomon-Bloembergen-Morgan equations that takes angles and distances into account. Optical spectroscopy was also performed to determine the Racah parameters and energy level separations of these complexes. In addition, three chapters detail other spectroscopic work performed by the author. Chapter 4 details a reexamination of the spectroscopy of a series of heteroscorpionates that provides new insight on the electron paramagnetic resonance of pseudotetrahedral Co(II). Chapter 5 discusses a trinuclear iron complex and spectroscopic evidence that the iron nuclei are antiferromagnetically coupled. Chapter 6 discusses optical and NMR spectroscopy of the Fe(II), Ni(II), and Co(II) versions of a five coordinate complex
