Background
Nuclear magnetic resonance NMR spectroscopy is a sensitive chemical analytical technique which detects the magnetic properties of certain atoms such as hydrogen and carbon. The resulting spectrum can be compared against a database of known NMR signatures to identify atoms or functional groups in sample mixture. A typical application is to use NMR to prove that a sample pure or has completed a reaction.
Significance
Protons create different resonance spikes depending where they are located on the molecule.
Operation
This provides instructions for a Bruker Advance 300 NMR.
