Ir stretch at 3000
Web[1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound. The absorptions in this range do not apply only to bonds in organic molecules. WebThe sp3 C-H stretching vibrations are just to the right of 3000cm-1 and since it is an internal alkyne, there is no sp C-H near 3300cm-1. 3b. A terminal alkyne, hex-1-yne, HC≡CCH2CH2 CH2CH3. Note that the terminal alkyne is more polar and the C≡C is obvious (medium intensity, (near 2100cm-1)..
