WebIn a ¹H NMR experiment, the heights of the peaks are not what matters. The relative areas of the peaks are the same as the relative numbers of protons in different environments. For example, if you have three peaks with relative areas 1:2:3, it means that your molecule has three different types of H atom, and their numbers are 1, 2,and 3 or 2 ...
