摘要：

Substrate and surface pressure dependencies of the molecular orientation and structure of arachidic acid monolayer films have been investigated by infrared transmission and reflection-absorption (RA) spectroscopy. The following conclusions can be reached in the present study: (1) The structure of arachidic acid monolayer films deposited on CaF2 plates changes with the surface pressure; for example, the subcell packing of the hydrocarbon chains changes from hexagonal to orthorhombic for pressure increasing from 20 to 30 mN/m. (2) The structures of the films deposited on Au-evaporated glass slides do not show a marked dependency on the surface pressure, but the fraction of the trans-configuration for the C(beta)-C(alpha)-C=O group increases with the pressure.
