I. GENERAL INTRODUCTION
In this paper, adsorption isotherms and adsorption phenomena, especially those related to the dynamic state of the molecules of medium-sized normal alcohol vapors adsorbed in multilayer adsorption above monolayer adsorption on various solid surfaces, are described. In general, since the molecules in multilayer gas adsorption are considered to be in a molecular state analogous to the liquid state at the same temperature and pressure, the dynamic state of the liquid molecules near the liquid/solid interface may be considered similar to the state of the multilayer gas adsorption molecules.
