Interpretation Introduction

Interpretation: The expected splitting pattern for each of the three signals to be predicted.

Concept Introduction:

Coupling constant:

  1. 1. When a splitting of each signal occurs the distance between the individual peaks on the splitting pattern is termed as coupling constant (J) and measured in hertz. Coupling constant depends on the kind of neighboring protons involved but not on the operating frequency of spectrometer.
  2. 2. When the two kinds of protons (subjected protons and neighboring protons) are splitting to each other the coupling constant will be same for both signals.

Mutiplets:

When the proton couple with different kinds of neighboring protons, the splitting pattern is highly complex thus gives the overlapping of the signals having complex splitting pattern termed as Mutiplets.

The appearance of the signal will depend on the value of J.
