A quantitative relationship of mass dependent interaction between surface hydroxyl groups of silica and adsorbed molecules are derived from the charge transfer theory of the hydrogen bond. Also, relationship between ionization potential, I and mass, m, of adsorbates are established as I^-2∞ -log m. These relationship are well established not only in the adsorption system of alkylbenzenes halogenobenzenes and chloromethanes but also in inert gases and n-alkanes which are weakly hydrogenbonded and in pyridine derivatives which are strongly hydrogenbonded with silica. Adsorption mechanism can be characterized from slopes of the relationship by plotting I^-2 against -log m. In polymer system, surface energies interacting with silica can be related with monomeric masses and that of monomeric structure of corresponding polymers.
