implicated as playing a major role in modulating electrostatic interactions via through-space and polarization effects, but these phenomena are often hard to dissect. By using synthetic molecular torsion balances and a simple explicit solvation model, we demonstrate that the solvation of substituents substantially affects the electrostatic potential of aromatic rings. Although polarization effects are
溶剂效应被认为在通过空间效应和极化效应调节静电相互作用中起主要作用,但这些现象通常很难剖析。通过使用合成分子扭转平衡和简单的显式溶剂化模型,我们证明取代基的溶剂化显着影响芳环的静电势。虽然极化效应很重要,但我们表明一个简单的附加空间模型也提供了对实验数据的合理解释。结果提供了对溶剂结构的见解,并可能有助于开发计算成本低廉的溶剂模型。
