S. Sodergren et al., Surface structures of solutions of tetrabutylammonium nitrate studied by core electron spectroscopy, ACT CHEM SC, 53(9), 1999, pp. 737-740
Angular resolved core electron spectroscopy has been applied to the study o
f solutions of a surfactant onium salt (tetrabutylammonium nitrate) in form
amide. The effect of dissolving CsI into the surfactant system was studied
as a function of concentration. The electron spectra, correlated to observe
d surface tension changes, were interpreted in terms of direct involvement
of iodide ions in double-layer screening at the vacuum-solution interface.
