Figure 5: Selected regions of the FTIR spectra for the CTAB molecule. (a) C–H stretching vibrational features; (b) methylene scissoring vibration and asymmetric bending mode of the head [N(CH3)3] methyl group. (c) CH2 wagging region; (d) C–N stretching vibrational modes. The spectra refer to the CTAB packing densities: ; ; ;  molecules cm−2.
