Paper Abstract

FT-IR spectra of lauric acid in different media were examined. In very dilute solution of lauric acid in CC14, the two bands at 1711 and 1760 cm-1 the region 1650 to 1800 cm-1 were observed for the C=0 stretching modes of dimer and monomer of lauric acid, respectively. In n-butanol KBr pellet and fluorinated hydrocarbon media, the three bands at 1712, 1701 and 1687 cm-1 after deconvolution and curve analysis for the C=0 stretching mode can be observed. In the region of C-H stretching vibration, the wavenumber shifts of the CH2 symmetric and antisymmetric stretching bands of lauric acid in different media show that the packings of acyl chains of lauric acid in different media are not the same.
