Define coupling constant in NMR. How it is calculated? (short question)
Accepted Answer
In NMR, the coupling constant (J) is a measure of the interaction between two magnetic nuclei. It's represented in Hertz (Hz) and reflects the strength of the interaction between those nuclei.
Calculation: J is typically measured directly from the NMR spectrum by determining the distance (in Hz) between the peaks in a multiplet.
Note: The coupling constant is independent of the strength of the applied magnetic field.
