Difference spectra,mixed micelles

Figure 10 Difference spectra in the S-O stretching region obtained by subtraction of the spectrum of SDS micelles in water (hemispherical endcap environments) from the mixed micelles of 0.3 M DTAC/SDS (T = 23°C). Also pictured is a difference spectrum from the SDS/NaCl study. Reprinted from ref. 47. Copyright 1990 American Chemical Society.

Figure 13 Difference spectra in the S-0 stretching region for 10 wt.% C14AO/SDS mixtures (T = 20°C). Also pictured are difference spectra from DTAC/SDS mixed micelles, and SDS/NaCl mixtures, and the spectrum of SDS micelles in water (Reproduced with permission from ref. 49.

Figure 11 FTIR spectra of the CH3-N and CH2 deformation region in mixed micelles of DTAC/SDS-d25. From top, X3P3 = 0.86, 0.20, 0.0. The bottom spectrum is a difference spectrum with pure DTAC micelles subtracted from the SDS = 20 sample (T = 23 C). Reprinted from ref. 47. Copyright 1990 American Chemical Society.
