WebFT-IR spectroscopy was used to identify the functional groups present in the reactants and products while NMR spectroscopy was used to determine the organic framework of the molecules. First, the IR spectra for the aspirin synthesis were acquired (Figure 6). From the top of the spectra stack to the bottom, the salicylic acid reactant, WebExpert Answer. 90% (21 ratings) Transcribed image text: Assign the peaks in the infrared spectrum of aspirin (below) with frequencies greater than 1500 cm^-1 to specific bond vibrations AND the functional group the bond is associated with. Clearly indicate the specific bond vibration that is associated with the relevant peaks.

WebTo use an IR spectrum table, first find the frequency or compound in the first column, depending on which type of chart you are using. Then find the corresponding values for absorption, appearance and other attributes. The value for absorption is usually in cm -1. Note that not all frequencies have a related compound.
