Assigning NMR Spectra

Page Author: Lucy Walker

Assigning NMR spectra is a key aspect of chemistry research. We use it to confirm the identity of compounds and deduce the structure of new ones.

Introduction

Here undergraduate student Lucy Walker talks us through the background of how NMR works and how it gives us information about organic molecules.

Test your knowledge of NMR theory using this multiple choice quiz.

13C NMR

Lucy talks us through how we assign 13C or carbon NMR of organic molecules. This includes chemical environments, chemical shifts and symmetry.

1H NMR

Lucy talks us through how we assign 1H or proton NMR of organic molecules. This includes chemical environments, chemical shifts and coupling including the n+1 rule.
