The chemical shifts of each type of proton are to be determined. Concept introduction: The chemical shift is defined as the difference in parts per million in the absorption spectrum of a particular proton from the absorption position of a reference proton. Tetramethylsilane is taken as the reference proton. Chemical shifts are measured in parts per million, and it is dimensionless quantity.
