AbstractA theoretical model is presented to study the phase transition of molecular orientation in a Langmuir monolayer on air–water interface. The polar molecules are treated as rodlike dipoles with three types of interactions; short-range steric repulsive interaction among the molecules, polar interaction between the molecules and water surface, and dipolar interaction among the molecules. The orientational order parameters, 〈cos θ〉 and 〈(3 cos 2 θ- 1)/2〉, are calculated as functions of the molecular density and temperature. It is shown that compressing the molecular area will lead to a continuous phase transition of the molecular orientation. ©1997 American Institute of Physics.
