硬脂酸Langmuir Blodgett膜的FTIR研究
摘要:
本文首次测得3—11层硬脂酸LB膜的FTIR-T光谱与测得的1—11层LB膜FTIR-ATR光谱对照表明, 透射技术简便易行, 两种技术研究LB脂结构, 可以起到相互补充的作用, 对于复杂体系LB膜, 两种方法对应的谱带强度比是获得分子片断取向的重要手段。

FT-IR Spectroscopic Study on Langmuir-Blodgett Films of Stearic Acid
Abstract:
FT-IR transmission spectra of the 3—11 monolayer Langmu ir-Blodgett(LB) films of stearic acid, have been observed compared with FT-IR ATR spectra. As an easily feasible technique, transmission method can offer supplementery information to the ATR one. The intensity ratios between the vibrational bands obtained by the two methods give the orientation aspect of molecular fregments of complecated LB films.
