摘要：

While it is generally accepted that surfactants adsorb at the interface between water and a hydrophobic surface with their nonpolar parts in contact with the hydrophobic surface and their polar regions oriented toward the water, this orientation has never been experimentally verified. In this paper, infrared-visible sum-frequency spectroscopy is used to demonstrate that dodecanol adsorbs from aqueous solution onto a hydrophobic surface (a monolayer of octadecanethiol on gold) with the terminal methyl group of the dodecanol oriented toward the hydrophobic surface.
