Calculation of the Coupling Constant; This is a simple example that illustrates how to calculate the chemical shift of a doublet and how to determine the coupling constant (the J value) for such a signal. This example requires that you have the peak values for the two peaks of the doublet:6.7978 ppm7820 ppmMultiplicity:DoubletChemical Shift:Doublet; the average of the two peaks, the value of interestExample: (6.7978 ppm 6.7820 ppm)/2 = 6.79 ppmJ value:The coupling constant is measured as the s
