+The FTIR spectra of the extract and the corrosion products are presented in [[#f0005|Figure 1]] and [[#f0010|Figure 2]]. The spectra show the presence of hydroxyl (O&mdash;H) and unsaturated (C═C) functional groups which are known to have inhibitory properties [[#b0075|[15]]]. Similar FTIR spectra have also been reported for ''Tithonia Diversifolia''[[#b0035|[7]]]. It is observed that there is a shift in the spectra of the extract when mild steel was immersed in it to form corrosion product. The hydroxyl (O&mdash;H) group shifted from 3379 to 3440 cm<sup>−1</sup> while the unsaturated (C═C) band shifted from 1635 to 1640 cm<sup>−1</sup>. This is an indication that there is an interaction between the extract and the mild steel substrate which resulted in inhibition. Alaneme et al. [[#b0075|[15]]] reported that the shifts in the spectra suggest that the extracts (through the functional groups) interact with the mild steel surface forming a protective complex which promotes the inhibition of the metal from attack in the acidic medium.
