Two different types of proton in the table 16-1 whose absorption peaks appear downfield and two that appear upfield from those produced by the proton in CH 3 Cl are to be determined. Concept introduction: Nuclear magnetic resonance spectroscopy, NMR, is a powerful technique to determine the nuclear spin and the splitting of energy levels in a magnetic field. NMR is used for the testing on the nuclei of atoms. A proton’s chemical shift is the same regardless of the NMR instrument used to measure it. The protons in different chemical environments give different signals in an NMR spectrum. The chemical shifts observed in 1 H NMR spectroscopy show that different proton chemical shifts are governed by the identity of the surrounding atoms.
