Infrared reflection absorption spectroscopy (IRAS) and x-ray photoelectron spectroscopy (XPS) have been used to study the adsorption of potassium p-methyl benzyl xanthate and potassium p-trifluoromethyl benzyl xanthate on gold surfaces. Monolayer structures were formed by adsorption from 1 to 10 μM aqueous solutions of the xanthates for different adsorption times. The reflection-adsorption (R-A) spectra...
The concentration dependence of the infrared spectra of CCl4 solutions of AOT [bis(2-ethylhexyl)sodium sulfosuccinate] has been determined in a concentration range (0–1.6 mM) encompassing the critical micelle concentration (CMC ≃ 0.2 mM). — Effects detected on the molar extinction coefficients of the bands due to C-H stretching vibrations can be used as indicators of micelle formation. — The same...
