WebMar 5, 2024 · $3391.66 cm ^{-1}$ is the asymmetric stretch of the $\ce{N-H}$ in the amide. $3184.80 cm^{-1}$ is the symmetric stretch of the $\ce{N-H}$ in the amide. From previous understanding, I was aware that the asymmetric stretch requires more energy, and hence a higher wavenumber than the symmetric stretch. WebC–C stretch (in-ring) from 1600-1585 cm-1; C–C stretch (in-ring) from 1500-1400 cm-1; C–H “oop” from 900-675 cm-1; Note that this is at slightly higher frequency than is the –C–H stretch in alkanes. This is a very useful tool for interpreting IR spectra. Only alkenes and aromatics show a C–H stretch slightly higher than 3000 cm-1.
