The C-O-C linkage can also undergo a symmetric stretch as shown in the right side of Figure 2. This peak is typically not as intense as the C-O-C asymmetric stretch because du/dx for the symmetric stretch is less than that for the asymmetric stretch (3). This peak typically falls between 890 and 820.IR Spectroscopy Tutorial: Esters.
