英文摘要	With Maxwell displacement current (MDC) measurement coupled with optical second harmonic generation (SHG) measurement, the dielectric polarization phenomena of monolayers can be examined. We have been developing a novel MDC-SHG experimental system, and analyzing the dielectric monolayers at the air-water interface. From theoretical side, based on a rod molecule model, formula to express the linear and nonlinear polarization of monolayers with C-infinity-symmetry have been derived using orientational order parameters. On the other hand, using the developed experimental system, the orientational order parameter has been determined with surface pressure-molecular area isotherm (pi-A isotherm) for liquid crystalline monolayers. Further, phase transitions of monolayers that accompanies the monolayer structural change has been successfully detected. (c) 2004 Elsevier B.V. All rights reserved.
