Relationship between the Area of a Peak and Molecular Structure

1 Relationship between the Area of a Peak and Molecular Structure 

As we learned in Section 3.4, the multiplicity of a given peak tells us the number of adjacent equivalent protons. The multiplicity tells us nothing about the number of protons that give rise to the peak itself. That information comes from the peak area. The total area of an absorption peak is directly proportional to the number of protons that resonate at the frequency. By total
