Figure 15. Stacked FTIR spectra for pure short chain (C1–C4) alkyl salicylate esters showing the fingerprint region only. MS, ES, PS, and BS are represented by red, blue, green, and black lines, respectively. The absorbance bands unique to methyl, ethyl, and propyl salicylates used for quantification (labelled and filled in) are between 1435–1445 cm^-1, 1365–1375 cm^-1, and 930–940 cm^-1, respectively
