中文摘要the monolayer of the mixture of octadecanoic acid and octadecylamine with molar ratio 1: 1 has been investigated at the air-water interface. it was found that the monolayer shows a rather stable state at the surface pressure of 30 mn/m and this monolayer can be transferred onto a caf2 plate by langmuir-blodgett (lb) technique. the infrared spectra of lb films indicated that octadecyl ammonium octadecanoate is formed by an intermolecular proton exchange between adjacent carboxylic and aminic groups (coo- and nh3+). in three-layer lb film, the ch2 scissoring mode of the long hydrocarbon chains of octadecyl ammonium octadecanoate shows a broad band feature at about 1468 cm(-1) while this vibrational mode of three-layer lb film of the mixture (1: 1) of deuterated stearic acid and octadecylamine (octadecylammonium octadecanoate-d35, c18h37nh3+c17d35coo-) only shows a narrow band. the broad feature of the ch2 scissoring mode in octadecylammonium octadecanoate probably originates from the coupling between the chain of stearic acid and that of octadecylamine while this kind of coupling could be completely removed in octadecylammonium octadecanoate-d35.
