Ir spectra of vanillin
WebThe spectrum of vanillin shows this for the phenolic hydroxyl, which is hydrogen bonded to the adjacent ether oxygen. Alcohols also display C-O stretching absorption at 970 to 1250 -1. This is marked in the preceding spectrum along with the ether C-O absorptions; and the following spectrum of cyclohexanol shows two such absorptions, coming from ...
