Introduction to Spectroscopy In previous sections of this text the structural formulas of hundreds of organic compounds have been reported, often with very little supporting evidence. These structures, and millions of others described in the scientific literature, are in fact based upon sound experimental evidence, which was omitted at the time in order to focus on other aspects of the subject.
Much of the most compelling evidence for structure comes from spectroscopic experiments, as will be demonstrated in the following topics. The Light of Knowledge is an often used phrase, but it is particularly appropriate in reference to spectroscopy. Most of what we know about the structure of atoms and molecules comes from studying their interaction with light (electromagnetic radiation). Different regions of the electromagnetic spectrum provide different kinds of information as a result of such interactions. Table of Contents. Society for Applied Spectroscopy. SciFinder. Dotmatics.
