The H NMR spectra of amides (1) have some interesting quirks. One quirk is that the N-H protons of primary and secondary amides (e.g. 2) are quite broad and appear at relatively high but variable chemical shifts (5-9 ppm). Another "quirk" is that identical N-R groups (e.g R2 groups in 3) can appear at different chemical shifts even though the same groups in a ketone analog...
