O acoplamento vicinal entre os dois prótons de metileno produziu um padrão característico de quarteto no espectro de RMN
2. The coupling constant (J) that quantifies this interaction, typically denoted as ³J and measured in Hertz (Hz)
The vicinal coupling constant was determined to be 7 Hz, indicating a trans-diaxial relationship
A constante de acoplamento vicinal foi determinada como 7 Hz, indicando uma relação trans-diaxial
This is a specialized technical term used primarily in organic chemistry, biochemistry, and analytical chemistry. It is essential terminology in academic and industrial laboratories across both Brazil and Portugal, particularly in pharmaceutical development, materials science, and structural analysis.
