HOW TO DRAW A COUPLING TREE IN NMR

Coupling tree is a pattern developed as a result of the splitting of signals in 1H-NMR due to spin-spin coupling. The tree tells us about the splitting pattern of the signal and also helps in calculation of the coupling constant.

SIGNAL GENERATION IN NMR

We know that a spin active nucleus behaves as a tiny magnet under the influence of a strong magnetic field. Such nuclei have an intrinsic property of arranging themselves in all possible spin states in the presence of a magnetic field. The possible spin states can be calculated from the spin quantum number.
