C=O stretch 1860 ± 20 cm-1 1800 ± 15 1800 ± 15. Conjugation lowers the C=O frequencies reported here, as with aldehydes & ketones. In acyl chlorides a lower intensity shoulder or peak near 1740 cm-1 is due to an overtone interaction. Acid Anhydride, (RCO) 2 O acyclic 6-membered ring 5-membered ring. C=O stretch (2 bands) 1750 & 1820 cm-1The 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).

To improve the quantification of oxygen content in the deconvoluted C 1s spectra, Smith et al. proposed a method based on a 7-peak C 1s deconvolution (3 C–C peaks, 3 oxygenated peaks, and π-π∗ transition peak), which resulted in C:O ratios in good agreement of those obtained from total C 1s and O 1s spectra.

Other significant transmittance peaks at 1025, 1532, 2350, 2920, and 3220 cm-1 correspond to C-O stretching, N-H stretching (presence of primary amine), -C-H stretching, and the presence of -OH/N ...Figure 8. shows the spectrum of 2-butanone.

Peak A at 1261 is the symmetric ring breathing vibration. Note that this falls in the range where C-O stretching peaks traditionally fall. Peak B at 904 is the asymmetric C-O-C stretch, and peak C at 831 is the symmetric C-O-C stretch. Note how intense peaks B and C are, and that they fall at a relatively low wavenumber.
