jjcoupling
jjcoupling refers to the interaction between the magnetic moments of two or more nuclei in a molecule, leading to the splitting of nuclear magnetic resonance (NMR) spectral lines. This phenomenon is a fundamental concept in NMR spectroscopy, a technique widely used in chemistry, biochemistry, and materials science to study molecular structure and dynamics.
The coupling arises from the indirect transmission of magnetic interactions through bonding electrons, often referred to
In proton NMR (¹H NMR), J-coupling is commonly observed between adjacent hydrogen atoms, such as in ethyl
Advanced techniques like INEPT (Insensitive Nuclei Enhanced by Polarization Transfer) and DEPT (Distortionless Enhancement by Polarization
In summary, jjcoupling is a critical tool in NMR spectroscopy, enabling detailed structural characterization by revealing
