On May 15-18, 1961, the 12th Annual Symposium on Spectros- copy was held
in Chicago. Over the twelve-year history of this meeting, it has
continually grown and now ranks as one of the major technical meetings
in the field of spectroscopy. The scope of the program itself represents
a balance between research applications and control applications,
between applied and the more fundamental aspects of spectroscopy. Papers
are presented each year in the specialty areas of X -ray, ultraviolet,
visible, infrared, Raman, EPR, and NMR spectroscopy. In many instances
over the years, excellent work has been re- ported at this symposium and
no further publication was made. These reports were then essentially
lost for further reference. It is the purpose of this publication to
provide a source of reference for the papers presented at the 12th
Annual Symposium. This first attempt at publishing a proceedings does
not include the entire program. Several papers could not be given
company clear- ance for publication, and several more were intended for
verbal presentation only and were never written for publication. I, as
Coordinator of the Symposium, would like to express my gratitude to the
Symposium Committee, John Ferraro, Elwin Davis, Joseph Ziomek, John
Kapetan, L. S. Gray, Jr., Russell J. Hansen, J. A. Sheinkop, L. V.
Azaroff, and Carl Moore, whose diligence and labor resulted in a truly
fine symposium, and subsequently made pos- sible this publication.
