摘要：

The structure of monolayers of CH3(CH2)22COOH on water, along approximately 21-degrees-C isotherms between 18 and 35 angstrom2/molecule, has been studied with glancing-angle x-ray diffraction and specular reflection. Following an incremental area change, in some regions of the isotherm, the diffraction pattern evolves until the surface pressure pi is relaxing less-than-or-similar-to 0.01 dyn/cm h. Reentrant behavior between tilted and nontilted phases is observed. Phase coexistence is indicated by differences between the deposited area/molecule and the area of the x-ray-determined unit cell.
