本文用表面力装置研究了原子级光滑云母表面间的单链醇（正辛醇和十一醇）薄膜的结构。接触角测量和光学和频产生用于额外的表征。在这两个系统中，底物-分子相互作用导致在每个表面上强烈结合的第一层。额外的液体组织成高度可压缩的双层，其可以通过施加足够高的压力而被排出。
The structure of thin films of simple chain alcohols (1-octanol and 1-undecanol) confined between two atomically smooth mica surfaces has been investigated using a surface forces apparatus. Contact angle measurements and optical sum frequency generation were used for additional characterization. In both systems, the substrate-molecule interaction leads to a strongly bound first layer on each surface. Additional liquid organizes into highly compressible bilayers, which could be expelled by applying sufficiently high pressure.
