How calculate coupling constant of triplet of doublet?

Answer 1

To calculate the coupling constant of a triplet of doublet in NMR spectroscopy, you can analyze the splitting patterns in the spectrum. A triplet of doublets indicates that a proton is coupled to two equivalent protons (forming a triplet) and these two protons are also coupled to another set of protons (forming a doublet). Measure the distance between the peaks in the triplet and doublet patterns to determine the coupling constants (J values) using the formula ( J = \frac{\Delta \nu}{\text{n}} ), where ( \Delta \nu ) is the frequency difference between peaks and ( n ) is the number of equivalent protons. The resulting values will give you the coupling constants for the respective interactions.
