Infrared Spectroscopy. Ethers are difficult to identify by IR spectroscopy. Although they show an absorption due to C–O single-bond stretching in the range 1050 to 1150 cm –1, many other kinds of absorptions occur in the same range. Figure \(\PageIndex{1}\) shows the IR spectrum of diethyl ether and identifies the C–O stretch.

chem.libretexts.org/Bookshelves/Organic_Chemistr…Although there are many peaks in the spectrum of diethyl ether, the only one that is diagnostic for it being an ether is the C-O-C asymmetric stretch labeled A at 1122. For saturated ethers, generally this peak falls at between 1140 and 1070.

在spectroscopyonline.com上查看更多信息Since all ethers contain a C-O-C linkage, the vibration that we would usually refer to as a “C-O” stretch actually involves the asymmetric stretch of the C-O-C moiety as shown in the left side of Figure 2. This vibration is analogous to the C-C-O asymmetric stretch of alcohols, and like alcohols these peaks are typically the lar…IR Absorption Frequencies - NIU - Department of Chemistry and …
