Apply for or manage your medical, food, cash or other State of Colorado benefits. News. View All News. For example, the most characteristic absorption band in the spectrum of 2-hexanone (Figure 6.3a) is that from the stretching vibration of carbonyl double bond C=O at 1716 cm-1. It is a very strong band comparing to the others on the spectrum. A strong absorbance band in the 1650–1750 cm-1 region indicates that a carbonyl group (C=O) is present.

It is therefore relatively easy to identify the aldehyde group (together with the C=O stretching at about 1700 cm-1) since essentially no other absorptions occur at these wavenumbers (see the example of the IR spectrum of butanal in Figure 6.4d). The stretching vibration of triple bonds C≡C and C≡N have absorption bands of about 2100–2200 ... The region of the infrared spectrum from 1200 to 700 cm -1 is called the fingerprint region. This region is notable for the large number of infrared bands that are found there. Many different vibrations, including C-O, C-C and C-N single bond stretches, C-H bending vibrations, and some bands due to benzene rings are found in this region.

This strategy places a C O peak at 531.2–531.6 eV with an aliphatic C O group positioned at 532.5–532.9 eV and aromatic C O positioned near 533.0–533.4 eV. These positions are consistent with those reported by other groups [54]. The assignment of adsorbed moisture and oxygen is variously assigned between 533 and 535 eV.
