WebIf a compound is suspected to be an aldehyde, a peak always appears around 2720 cm-1 which often appears as a shoulder-type peak just to the right of the alkyl C–H stretches. Figure 9. shows the spectrum of butyraldehyde. The carbonyl stretch C=O of esters appears: Figure 10. shows the spectrum of ethyl benzoate. WebIR SPECTRUM OF A CARBOXYLIC ACID. A carboxylic acid functional group combines the features of alcohols and ketones because it has both the O-H bond and the C=O bond. Therefore carboxylic acids show a very strong and broad band covering a wide range between 2800 and 3500 cm-1 for the O-H stretch. At the same time they also show the …

WebFourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures … Web(This peak usually appears much broader than the other IR absorptions. 3400-2400 (This peak always covers the entire region with a VERY BROAD peak.)
