英文摘要: On the basis of the interaction of dipolar molecules with a liquid surface we calculate the thermodynamics of the molecular orientation and related mechanical and electric effects for a monolayer of molecules on an air-liquid interface. It is shown that compressing the molecular area should lead to a weak first order phase transition of the molecules from isotropic to polar orientation. Although the main source of the phase transition may not be the polar interactions, the polar nature of the molecules offers a nice way of monitoring the phase transition. The anomalous slope of the pressure-area isotherms is found to be related to the transition. It was shown theoretically that a Maxwell displacement current with a sharp pulse shape is generated at the onset of the transition.
