✦ Synopsis

A contactless electrical method is presented which enables the detection of displacement currents in a monolayer of organic molecules forming a 2D system at the air/water interface in the Langmuir trough. The technique provides a deep insight in the dynamic behaviour of a monolayer of molecules possessing a permanent dipole under increasing or decreasing surface pressure. The dipole moment of the molecule in a monolayer could be calculated. D. Baranc Ïok et al.: Contactless Detection of the Orientation of Molecules
