Vibrational Spectroscopy: Instrumentation for Infrared and Raman Spectroscopy∗

Abstract In reviewing the contents of this article, a decision had to be made regarding the presentation of the techniques for infiared and Raman spectroscopy. The problem lies in the complementary nature of these two techniques and the significant amount of overlap in both the instrumentation and the applications. It was decided that the audience would be served better if the two techniques were presented side-by-side within the same chapter. In this way, the similarities and dissimilarities can be assimilated conveniently, and for a person new to vibrational spectroscopy, it provides a more even-handed approach to these two powerful methods of analysis. However, having made the case for combining the techniques into a single chapter, the integrity of the techniques will be retained where necessary, and the individual techniques will be discussed separately, if appropriate. ∗Originally appeared in Analytical Instrumention Handbook, G.
