Chapter 13: Spectroscopy

Summary

Modern spectroscopic methods have largely replaced chemical tests as the standard means of identifying chemical structures, and for a practicing practical organic chemist ¹H-NMR has become a routine tool for identifying the products of reactions.

Spectroscopic techniques are fundamentally based on the molecules absorbing energy then monitoring the affect this has on the molecule.
