Splitting diagram for proton H b has to be drawn. Concept introduction: The Single 1 H NMR signal is split into multiple peaks called the multiplicity of the signal. Splitting of signals is done according to the ( N + 1 ) ) rule. N is the number of adjacent non-equivalent protons. According to the ( N + 1 ) rule, for a proton-coupled with N adjacent non-equivalent protons, the signal split into ( N + 1 ) peak. The splitting is mutual. Splitting occurs only due to non-equivalent protons that are the protons present in the different chemical environment. The distance between any two adjacent peaks is called coupling constant in hertz represented as J . The value of coupling constant for two protons coupling with each other is same. Thus the coupling constant gives vital information about the adjacent groups or protons because protons on adjacent carbons have a similar coupling constant.
