How to Calculate Coupling Constant (J values) in Proton NMR Spectroscopy

Hi Friends, in this article we will see how to calculate coupling constants (J values) in 1H-NMR Spectroscopy.

Key wordsCoupling constant, Multiplicity1H-NMR spectrum, Signal.

Definition of coupling constant

The coupling constant is a distance between sub-peaks expressed in hertz. In 1H-NMR spectrum a peak splits into multiple sub-peaks due to coupling with neighboring protons. The value of coupling constant does not depend upon frequency of machine and solvent used for NMR experiment.

We have discussed various applications of spectroscopy in chemistry, medicine and environmental science in another article. Please check out for more details. [Link]
