Proton having greater chemical shift has to be identified. Concept Introduction: 1 H NMR spectroscopy: It is the study of the interaction between electromagnetic radiation and the nuclei of hydrogen atoms and the hydrogen atoms. Chemical equivalence: The number of different kinds of protons in different electronic environments causes the number of signals in a 1 H NMR spectrum. If the protons are in identical electronic environments, then they are said to be chemically equivalent and they produce only one signal.
