This volume presents a collection of papers given at the 16th Mid
-America Symposium on Spectroscopy held in Chicago, June 14-17, 1965.
The Mid-America Symposium is sponsored annually by the Chicago Section
of the Society for Applied Spectroscopy in cooperation with the St.
Louis, Niagara Frontier, Cleveland, Detroit, lndianapolis, and Milwaukee
Sections of the Society and the Chicago Gas Chromatography Discussion
Group. Although we refer to this meeting as the Mid-America Symposium,
it continues to attract attendance, interest, and inquiry from many
parts of the world. Sessions on lnfrared, Raman, Ultraviolet, Visible,
Emis- sion, Flame, Atomic Absorption, Nuclear Particle, Gamma Ray,
Nuclear Magnetic Resonance, X-Ray Spectroscopy, Spec- troscopy,
Spectrophosphorimetry, and Gas Chromatography provided interesting
papers involving both applied and theo- retical principles. This volume
continues a series of the Proceedings initiated in 1961 and is composed
of a collection of 37 papers presented at this meeting. It is the
opinion of the Symposium Committee that although not a complete account
of the proceedings, publication of this collection as a reference is
warranted. As editors of this volume, we wish to express our gratitude
to the authors who gave their time and effort in submitting their
manuscripts so that this volume could be published. The Symposium
Committee, L. S. Gray, W. Baer, Vivian Biske, W. Los eki, M. S. Wang, F.
