1H NMR Integrals and Proton Ratios

1H NMR integrals show how many protons contribute to each signal. In a proton NMR spectrum, the signal area is represented by a vertical line called an integral, and the value is written below it. This makes it easier to compare peaks and estimate proton counts.

To find the proton ratio, each int...

Integration or the area under each signal indicates the number of protons contributing to that signal.

For example, in the benzyl acetate spectrum, the area under each peak is shown as a vertical line called an integral, with the integral value listed under it.

Each integral value is divided by the smallest integral value to obtain...
