The adsorption phenomena of dibutyl phthalate (DBP) molecules on the Si surface were observed in detail using a highly sensitive quartz crystal microbalance (QCM) and a new method involving a sliding chamber system. As a result of the precise observation of the adsorption phenomena and an accurate decomposition analysis, the typical Langmuir adsorption phenomenon with a time constant of 350 s was observed following the rapid adsorption phenomenon that occurs within the first 10 s and the next adsorption phenomenon of increasing linearly. After almost reaching the adsorption equilibrium amount, another Langmuir adsorption phenomena for a time constant of 3000 s was also observed; the Langmuir adsorption phenomenon for a time constant of 350 s seems to be that of an isolated admolecule whereas that for 3000 s seems to be one where admolecule cohere by mutual migration on a surface.
