Abstract
The molecular state of Rhodamine B/Arachidic acid mixed LB film was analyzed from 3D model simulation. As a result, it was considered “the molecule of the film rotated, when the pressure was applied to the film”. It became explainable in respect of the result of the π-A curve. It was examined by relation between the average of roughness of the surface from the AFM. The film was stabilized, when Arachidic acid was more abounding. It seems to have the electron functionality which the LB film of the AA/Rb=1 in a good condition.
