AbstractOriented multilayers formed on a solid surface by alkanoates with different mono- and divalent counterions were investigated by polarized ATR FT-IR spectroscopy. In the alkali laurates the alkyl chains are tilted by 30–40° relative to the bilayer normal Sodium laurate forms a different subcell structure compared to that in the potassium, rubidium and cesium laurates. In calcium and cadmium laurate the chain tilt is less than 20°. Furthermore, due to the chelating capacity of the divalent ions, the plane of the carboxylate group is inclined by 30–40° relative to the bilayer normal Magnesium laurate does not form ordered multilayers on the solid surface.
