Interpretation: The chemical shift in the
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 a dimensionless quantity.
