Background

Error creating thumbnail: Unable to save thumbnail to destination

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. Non identical protons will exhibit individual peaks. But equivalent protons will couple to create a single stronger peak.
