The two peaks around 130 must be the two carbons at either end of a carbon-carbon double bond. The peak at just less than 170 is the carbon in a carbon-oxygen double bond.

In addition to the C-O peak, it is helpful to note if an IR spectrum has no C=O or O-H stretch peaks to confirms it is not aldehyde, ketone, or alcohol. If you look at an IR spectrum of dibutyl ether, you will see: there are the usual sp 3 C-H stretching and CH 2 bending modes at 2900 and 1500 cm-1. there is a strong peak near 1100 cm-1. This ...

In the FTIR spectra of formulation containing both norfloxacin and C934, the prominent band, found between 3550 and 3400 cm -1, was assigned to υO–H and polymeric hydrogen bonding [ Figure 5 ]. The peak at 2600–2500 cm -1 represented the υO–H of carboxylic acid, i.e., strong intermolecular hydrogen bonding. iii. Why does the dibenzalacetone C=O stretching vibration occur at a lower frequency than the 1720 cm-1 ketone C=O peak in acetone? (hint: it is the same reason that the benazaldehyde C=O peak at 1700 cm-1 is at lower frequency than the 3-methylbutanal C=O peak at 1727 cm-1 shown on p. 284 of Lehman's text; also note that the answer is given on p. 284 of Lehman’s text). Notice the absorption due to the C-H bonds just under 3000 cm-1, and also the troughs between 1000 and 1100 cm-1 - one of which will be due to the C-O bond. The infra-red spectrum for an ester. Ethyl ethanoate. This time the O-H absorption is missing completely. Don't confuse it with the C-H trough fractionally less than 3000 cm-1.Hydroxide contamination peak is due to the reaction with residual water in the lab air or the vacuum. The O (1s) BE of the hydroxide (water) contamination normally appears 0.5 to 1.0 eV above the oxide peak. Sodium (Na), Potassium (K), Oxygen (N) and Oxygen (Cl) are common trace to low level contaminants.Characteristic IR Absorption Peaks of Functional Groups* Vibration Position (cm-1) Intensity* Notes Alkanes C-H stretch 2990 – 2850 m to s Alkenes ...

In general, C-O stretching peaks are intense and normally fall between 1300 and 1000 cm-1 (going forward assume all peak positions are in cm-1 units). Because this wavenumber range is in the fingerprint region (2) there are often many peaks present between 1300 and 1000, but again the distinguishing feature of C-O stretches will be their intensity.

The C 1s and O 1s spectra for Pearls carbon in Figure 3e,f are typical of carbon-based materials, with peaks at 284.8, 286.2, and 288.8 eV, characteristic of C−C, C−O, and C O−C groups ...
