In contrast, the right half of the spectrum, below 2000 cm-1, normally contains many peaks of varying intensities, many of which are not readily identifiable. Two signals which can be seen clearly in this area is the carbonyl group, which is a very strong peak around 1700 cm-1, and the C-O bond with can be one or two strong peaks around 1200 cm-1.In general, for noncyclic saturated anhydrides the symmetric C=O stretch falls at 1820 ± 5 whereas the asymmetric stretch falls at 1750 ± 5. For noncyclic unsaturated acid anhydrides these peaks fall at 1775 ± 5 and 1720 ± 5, respectively. Note that based on their C=O stretching peak positions and the narrowness of the range where the peaks ...The peak at 284.70 eV can be attributed to C−C and C−H, and the C structure accounts for 69.08%; the peak at 285.54 eV can be attributed to C−O in ether and hydroxyl groups, accounting for ...Find free options for filing your taxes online, on your smartphone, or get help at an in-person Colorado site.

Figure 2: The infrared spectrum of zinc stearate (C 36 H 70 O 4 Zn).. Because carboxylates contain neither a C=O bond nor a C-O bond, they will not contain a carbonyl stretching peak around 1700 cm-1 (1) (going forward assume all peak positions are in wavenumber units), or a C-O stretch between 1300 and 1000 (5).
