Infrared spectroscopy
UV/Vis Spectroscopy
Proton NMR
Spectroscopy is the study of how light interacts with matter. We can use spectroscopy to determine the structure and functional groups in organic compounds. We will be learning about how to use IR, UV/Vis, and NMR spectroscopy.

Infrared spectroscopy

In this tutorial, Jay introduces the theory of IR spectroscopy and shows how to analyze simple IR spectra.
