WebFor 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. WebInfrared spectrometers, similar in principle to the UV-Visible spectrometer described elsewhere, permit chemists to obtain absorption spectra of compounds that are a unique …
