D-coupling
[/ˈdiː ˈkʌplɪŋ/]
nounpl: D-couplings
desacoplamento D
1. A technique in nuclear magnetic resonance (NMR) spectroscopy where deuterium (D or ²H) nuclei are decoupled from the observed nuclei, removing the fine splitting patterns caused by D-H coupling interactions
D-coupling experiments helped researchers simplify the NMR spectrum by removing deuterium splitting patterns.
Experimentos de desacoplamento D ajudaram pesquisadores a simplificar o espectro de RMN removendo padrões de divisão de deutério.
2. In mechanical engineering, the separation or disconnection of a deuterium-bearing component or system from another coupled system
The D-coupling of the two reactors prevented any thermal interference between them.
O desacoplamento D dos dois reatores evitou qualquer interferência térmica entre eles.
D-coupling is a specialized term primarily used in academic and industrial chemistry, physics, and materials science contexts. It is not commonly used outside scientific communities and appears predominantly in peer-reviewed literature, laboratory procedures, and technical documentation in both English and Portuguese-speaking countries.
