Deviations from the Nernst–Einstein relation are commonly attributed to ion–ion correlation and ion pairing. Despite the fact that these deviations can be quantified by either experimental measurements or molecular dynamics simulations, there is no rule of thumb to tell the extent of deviations. Here, we show that deviations from the Nernst–Einstein relation are proportional to the inverse viscosity by exploring the finite-size effect on transport properties under periodic boundary conditions. This conclusion is in accord with the established experimental results of ionic liquids.

粘度在能斯特-爱因斯坦关系偏差中的作用。
与能斯特-爱因斯坦关系的偏差通常归因于离子-离子关联和离子配对。尽管这些偏差可以通过实验测量或分子动力学模拟来量化,但没有经验法则可以告诉偏差的程度。在这里,我们通过探索周期性边界条件下输运特性的有限尺寸效应,证明了能斯特-爱因斯坦关系的偏差与反粘度成正比。这一结论与离子液体的既定实验结果一致。
