Web~2150 (v) For terminal alkynes, look for C-H stretch at ~3300 cm-1 The C≡C and C≡N stretches can be very difficult to distinguish because they both appear around 2150 cm-1. Terminal alkynes can be distinguished by the additional C-H stretch at ~3300 cm-1. 4. Alkene and Aromatic C=C Stretch Structural Unit Wavenumber, cm-1 Special Features 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.

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.
