使用基于二元混合物的布拉格-威廉姆斯理论的模型分析了由左手性和右手性手性对映体组成的混合朗缪尔薄膜，并讨论了混合效应对麦克斯韦位移电流（MDC）和表面压力面积等温线产生的贡献。结果表明，由于单层压缩过程中分子扭曲转变，左手性和右手性对映体分子之间的偶极-偶极相互作用，左手性和右手性对映体形成均匀且紧密的混合物，从而产生额外的MDC。
Mixed Langmuir films composed of the left- and right-handed chiral enantiomers are analyzed using a model based on the Bragg–Williams theory for binary mixtures, and the contribution of the mixing effect to the generation of Maxwell displacement current (MDC) and surface pressure-area isotherm is discussed. It is revealed that the formation of the homogeneous and intimate mixture of the left- and right-handed chiral enantiomers gives rise to the additional MDC generation due to the dipole–dipole interaction between the left- and right-handed chiral enantiomer molecules by the molecular twist transition during monolayer compression.
