摘要：

Isotherms of oxygen, argon, neopentane, tetramethylsilane, and diethyl ether on optically flat gold surfaces have been determined over the range 0-70 Brunauer-Emmett-Teller) (BET) monolayers, corresponding to 0-220 angstrom. The results are found to imply a potential energy of interaction U(Z) of the form U(Z) = alpha 1.74 x 10(-4)Z(-2) erg/molecule, where a is the molecular polarizability and Z the distance from the surface. The possible source of the disagreement between the experimental results and the theoretical predictions of Margenau, Bardeen, and Lennard-Jones is briefly discussed.
