C-o peak.

The peak at 66.75 ppm indicates there is a peak for carbon(s) in a carbon-oxygen single bond. The peak at 15.55 ppm indicates that there is a peak for carbon(s) in a carbon-carbon single bond. That would be consistent with C-C-O in the structure. It is not an alcohol (you are told that in the question), and the molecular formula is C 4 H 10 O ...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.The C=O stretching peak for isovaleraldehyde is at 1722, and in general for saturated aldehydes this peak falls at 1730 ± 10. For aromatic aldehydes the C=O stretch falls in a lower wavenumber range, from 1710 to 1685, because of conjugation (1).Graphene oxide has a complex C1s spectrum that includes sp 2, sp 3, C-O and C=O peaks. The sp 3 carbon and functionalized carbon of graphene oxide should be fitted with normal symmetric peak shapes. The sp 3 carbon peak should be ~0.9 eV higher than the sp 2 peak.

The wavenumber is defined as the reciprocal of wavelength (Formula 6.3), and the wavenumbers of IR radiation are normally in the range of 4000 cm-1 to 600 cm-1 (approximate corresponds the wavelength range of 2.5 μm to 17 μm of IR radiation).
