WebThe 1H NMR below are all for compounds with molecular formula of C5H12O (the relative integration area for each signal are given as numbers on the spectra). The IR spectra of these compounds do not have any strong band at above 3000 cm-1, nor are there strong bands at 1700 cm-1. WebNov 23, 2016 · Instead, IR is great for identifying certain specific functional groups, like alcohols and carbonyls. In this way it’s complimentary to other techniques (like NMR) which don’t yield this information as quickly. With this in mind, we can simplify the analysis of an IR spectrum by cutting out everything except the lowest-lying fruit.
