## The Basics of SpectroscopyThis ""Tutorial Text"" is intended to give readers a basic understanding of spectroscopy - the study of matter using electromagnetic radiation - and its uses as a scientific tool. The work begins with an abbreviated history of light and the interaction of light with matter. Spectrometer basics and the spectrum itself are discussed, along with quantitative mechanics, selection rules, and experimental factors. |
