From the standpoint of dielectric physics, investigations of the dielectric phenomena occurring in the organic ultra-thin films are absolutely necessity for the application of nanometric organic devices. In this paper, the dielectric polarization of organic monolayers at the air-water interface has been analyzed. The formula of polarization of organic monolayers is derived and it is expressed using orientational order parameters. It was revealed that Maxwell displacement current (MDC) measurement coupled with optical second-harmonic generation (SHG) measurement is helpful for the determination of the orientational order parameters. Monolayers of 8CB on the air-water interface were examined by MDC and SHG during monolayer compression. As a result, C_<∞v> symmetry was established for the 8CB monolayers by p-p, s-p polarized measurements.
