Abstract

Arachidic acid monolayers formed on an aqueous solution of cerium nitrate have been studied by grazing incidence X-ray diffraction. Despite compression beyond the collapse point, the monolayer unexpectedly retains its translational order and develops corrugation. This paper presents a method for simulating the two-dimensional diffraction patterns characteristic of monolayers with perturbed orientational order. The unusual diffraction data obtained from corrugated monolayers during synchrotron experiments are described using this approach.
