If there are two equivalent hydrogen atoms in the adjacent site, according to the n + 1 rule (n is the number of adjacent hydrogen atoms), the resonance peak of the hydrogen atom will split into a triple peak, which is caused by the combination of the spin orientations of the adjacent two hydrogen atoms.
As for the situation where multiple non-equivalent hydrogen atoms are adjacent, it is more complicated. It is necessary to consider the difference in the coupling constant of each adjacent hydrogen atom, and comprehensively analyze the change of the multiplicity of the referred hydrogen atom according to the principle of vector superposition.
Furthermore, the symmetry of the molecular structure also affects the multiplicity of specific hydrogen atoms. With a symmetric structure, some hydrogen atoms have the same chemical environment, and their multiplicity has its own rules.
To accurately predict the multiplicity of specific hydrogen atoms, it is necessary to deeply study the molecular structure, understand the interaction between atoms, and understand the coupling splitting mechanism in order to achieve its purpose.
