WebIn a well-resolved IR spectrum, yes. You have to keep an eye out for the C-C-O asymmetric stretch, found in the fingerprint region between 1000 and 1210 cm-1. Unsaturation on an adjacent carbon lowers the frequency of the C-O absorption. Therefore, primary alcohols usually have a C-C-O asymmetric stretch band between 1000 and 1075 cm-1. WebJan 1, 2024 · Figure 7: The infrared spectrum of ethyl alcohol obtained using the capillary thin film method. Because the hydroxyl group in alcohols engages in hydrogen bonding and hence will have broad peaks, it is easy to assign the peaks labeled A and E in Figure 7 as being from the -OH moiety.
