Dipolar Coupling

Dipolar coupling is a magnetic interaction between two magnetic nuclei, such as atoms with spinning nuclei, when they are close together. Think of it like two tiny magnets influencing each other's magnetic fields. In molecules, this interaction depends on how close the atoms are and their spatial arrangement. Dipolar coupling provides valuable information about the structure and distances within molecules, which is especially useful in techniques like solid-state NMR. It reveals how nearby nuclei communicate magnetically, helping scientists understand molecular architecture without needing to see the molecule directly.
