Spin-Spin splitting
Spin-spin splitting, also known as J-coupling, is a fundamental concept in atomic and molecular spectroscopy, particularly in nuclear magnetic resonance (NMR) spectroscopy. It arises due to the interaction between magnetic nuclei within a molecule. Each nucleus with a non-zero spin generates a small magnetic field that influences neighboring nuclei, leading to splitting of NMR __________ ____ _______ _________ ______ _______ ______.
