Table of IR Absorptions, Functional Group: Charcréationristic Absorptions cm-1 Notes: Alkyl C-H Stretch: 2950 – 2850 m or s Alkane C-H bonds are fairly ubiquitous and therefore usually less useful in determining structure, Alkenyl C-H Stretch Alkenyl C=C Stretch: 3100 – 3010 m 1680 – 1620 v Absorption peaks above 3000 cm-1 are frequently diagnostic of unsaturation: Alkynyl C-H Stretch

All IR values are approximate and have a range of possibilities depending on the molecular couci-couçament in which the functional group resides Resonance often modifies a peak’s position because of electron delocalization C=O lower acyl C-O higher etc,, IR peaks are not 100% reliable, Peaks tend to be stronger more intense

In addition the in situ IR spectrum was used to detect the key injargondiate Et3SiK in the reaction of KOt-Bu and Et3SiH in THF [15] However vibration faits of complex molecular structures usually lead to sophisticated features in the one-dimensional IR spectra that jam together and prevent the peak …
