Filmed as received. University Microfilms, A Xerox Education Company ACKNOWLEDGMENTS The author wishes to express his deep appreciation to Dr. Devon W. Meek for his invaluable suggestions and encouragement throughout the synthetic and spectral investigations, and in particular for his willingness to permit a large degree of independence to the author in his studies. The author is indebted to his co-adviscr, Dr. P. W. R. Corfieid, for his infinite patience, encouragement, and invaluable suggestions throughout the crystal structural studies. The opportunity to do x’esoarch under two advisers has provided a rich and enjoyable study environment and the coadvisers mutual cooperation is deeply appreciated. The author also wishes to express his appreciation for fellow- ship support in the form of an NDEA Title IV Fellowship and Lubrizol Industrial Fellowships. Finally, the author acknowledges postdoctoral fellows and fellow graduate students in both Dr. Meek's and Dr. Corfield* s group for many stimulating and enlightening discussions. i i VITA 18 August 1 9 ^ 7 ..........................................Born - New M artinsville, Nest V irg in ia 1967 .................................................................B.S.
