已经使用先前描述的方法研究了几种分子对的分子硫在饱和液-液界面上的扩散。界面电阻不直接取决于液体的极性，也不与界面张力相关。高电阻与表现出高度氢键的液体有关。通过适当的假设，可以计算出跨界面转移的活化自由能。看来，在涉及可忽略的阻力的系统中的转移类似于货车德瓦尔斯吸附，而对于涉及高阻力的系统，该过程与化学吸附相当。
The diffusion of molecular sulfur across a saturated liquid‐liquid interface has been investigated for several molecular pairs, using a method previously described. The interfacial resistance does not directly depend on polarity of the liquids, nor can it be correlated with interfacial tension. High resistances are associated with liquids which show a high degree of hydrogen bonding. With suitable assumptions it is possible to calculate a free energy of activation for transfer across the interface. It appears that transfer in systems involving negligible resistance is analogous to van der Waals adsorption, while for systems involving high resistance the process is comparable to chemisorption.
