He texted a friend that he …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. Log-In or Apply for Benefits | Colorado PEAK

Mar 1, 2018 · Note in Figure 5 that the high-wavenumber symmetric C=O stretching peak is weaker than the lower-wavenumber asymmetric C=O stretching peak. This pattern is opposite that for noncyclic anhydrides as seen above. Thus, the peak intensity ratio of the two anhydride C=O stretching peaks can be used to determine whether an anhydride is noncyclic or ...
