IR Tables, UCSC Table 1. Characteristic IR Absorption Peaks of Functional Groups* Vibration Position (cm-1) Intensity* Notes Alkanes C-H stretch 2990 – 2850 m to s Alkenes =C-H stretch 3100 – 3000 m C=C stretch 1680 – 1620 (sat.) 1650 – 1600 (conj.) w to m =C-H bend 995 – 685 s See Table 2 for detail Alkynes
16 Δεκ 2021 · The alkynes can generally be identified with the characteristic weak but sharp IR absorbance bands in the range of 2100-2250 cm-1 due to stretching of the C≡C triple bond, and terminal alkynes can be identified by their absorbance at about 3300 cm-1, due to stretching of sp C-H.
Table of IR Absorptions. All figures are for the typical case only -- signal positions and intensities may vary depending on the particular bond environment.
