DETAILED STRUCTURE OF THE HYDROCARBON CHAIN IN A SURFACTANT MONOLAYER AT THE AIR-WATER-INTERFACE - NEUTRON REFLECTION FROM HEXADECYLTRIMETHYLAMMONIUM BROMIDE

Abstract:

We have determined the structure of a monolayer of hexadecyltrimethylammonium bromide (C16TAB) adsorbed at the air/water interface at its critical micelle concentration (0.9 mM) at two levels of resolution achieved by isotopic labeling. We have labeled the surfactant molecule in blocks of four atoms (C4D8 or C4D9) and in blocks of two atoms (C2D4 or C2D5). We have measured the roughness of the layer and the set of separations between fragments labeled in blocks of two or four carbon atoms. Th...
