Webb1H NMR chemical shifts of 5.00 and 4.93 ppm. You might think that the resonance for the CH 2 protons would be split into a doublet by the lone CH proton (n+1 = 2), but you can see from the higher resolution spectrum, there are quite a few lines! What us happening is that each CH 2 proton is split by the other proton and by the lone CH proton.
