Calculated Spin-Spin Splitting Spectra

When you have adjacent protons the appearence of the proton NMR spectrum depends on 2 things.

a. The difference in chemical shift, between protons A and B.

b. The interaction between the protons that is called the coupling constant, J.

In this section you can see how the appearence of the spectrum changes with chemical shift at a constant value of the coupling constant, J.
