J-coupling
[/dʒeɪ ˈkʌplɪŋ/]
nounpl: J-couplings
acoplamento J
1. In nuclear magnetic resonance (NMR) spectroscopy, the indirect spin-spin coupling between nuclei mediated through bonding electrons, resulting in the splitting of spectral lines
The J-coupling constant between adjacent protons in the ethyl group is approximately 7 Hz.
A constante de acoplamento J entre prótons adjacentes no grupo etila é aproximadamente 7 Hz.
2. The coupling mechanism that provides information about the number and proximity of neighboring nuclear spins in a molecule
J-coupling patterns help chemists determine molecular structure and connectivity.
Os padrões de acoplamento J ajudam os químicos a determinar a estrutura e conectividade molecular.
This is specialized scientific terminology primarily used in academic and research contexts in both Brazil and the USA. It is particularly important in organic chemistry, biochemistry, and analytical chemistry curricula. The term originated from NMR spectroscopy research and remains unchanged across Portuguese and English-speaking scientific communities, reflecting the international nature of chemical nomenclature.
