Question
Chapter 13.9, Problem 13.12P
Interpretation Introduction
Interpretation: The splitting tree and the chemical shift of protons
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.
To determine: The splitting tree and the chemical shift of protons
