WebThe red protons have 1 neighbouring proton, the blue proton. Since there's only one neighbour it doesn't matter here. We expect 2 peaks in the signal (n=1, 1+1=2) and we see 2 peaks. The blue proton has two neighbouring protons, the red protons, and the two red protons are in the same environment as one another.
