Their spectra exhibit a series of three peaks from the stretching and contracting of the bonds in this ring that fall from 1280–1230, 950–810, and 880–750. The last two of these are particularly intense.

"WebSince C-H bonds don't hydrogen bond very well, you don't see that phenomenon in an ether, and an O-H peak is very easy to distinguish in the IR spectrum. Problem IR5.1. Even though there are only two C-O bonds in dibutyl ether, the C-O stretching mode is even stronger than the peak at 2900 cm-1 arising from 10 different C-H bonds. Explain why. " - Ether on ir
