Coupling

Definition

In the context of Nuclear Magnetic Resonance (NMR) Spectroscopy, coupling refers to the interaction between different nuclear spins that leads to the splitting of NMR signals into multiplets. This phenomenon is essential for determining the structure of organic compounds by providing information about the number and arrangement of neighboring hydrogen atoms.
