Abstract: The globe model for studying pendant drop in monolayer film has been established.Based on this model,the distributions are calculated for dipole intensity of fluorescent surfactant molecules,for surfactant molecular density and for fluorescent intensity along the observed direction.The calculation results are discussed and compared with the experiment on Octadecyl Rhodamine B(ODRB) molecules.

Key words: pendant drop, globe model, monolayer film, fluorescence image
