The 1 H-NMR spectra that we have seen so far (of methyl acetate and para-xylene) are somewhat unusual in the sense that in both of these molecules, each set of protons generates a single NMR signal. In fact, the 1 H-NMR spectra of most organic molecules contain proton signals that are ‘split’ into two or more sub-peaks.
