Dr. James A. de Haseth, Light Light Solutions, Athens, GA

COURSE DESCRIPTION
This one-day short course will present the origins of spectral bands in Infrared, Raman, and NIR spectroscopy. This will start with a discussion of the fundamental vibrations in mid-infrared and Raman spectra and explain how overtone and combination bands can appear in the NIR as well as in mid-infrared and Raman spectra.  Some direct guidelines will be presented to show which transitions are allowed.  This will not be a theoretical discussion, but rather an understanding of the physical phenomena that led to the development of the mathematical approaches.  Further topics include instrumental issues such as resolution, instrumental effects on spectral lineshape, and effects of mathematical manipulation of spectra.

WHO SHOULD ATTEND
This course is designed for scientists and engineers new to vibrational spectroscopy as well as practitioners who need a stronger understanding of vibrational spectra.  The focus of the course is on spectra and what information they convey.  The information content of the spectra will be explored.  The course is designed to help understand the benefits and limitations of the different spectrometries, including how to select the appropriate spectrometry to investigate specific problems and how information from more than one technique can expand the usefulness vibrational spectrometry.
