The carbonyl stretch C=O of saturated aliphatic aldehydes appears from 1740-1720 cm -1. As in ketones, if the carbons adjacent to the aldehyde group are unsaturated, this vibration is shifted to lower wavenumbers, 1710-1685 cm -1. See also:
WebIR Spectroscopy Tutorial: Alkynes. Alkynes are compounds that have a carbon-carbon triple bond (–C≡C–). The – C≡C – stretch appears as a weak band from 2260-2100 cm -1. This can be an important diagnostic tool because very few organic compounds show an absorption in this region. A terminal alkyne (but not an internal alkyne) will ...
