importance of London dispersion for structure and stability of molecules with less than about 200 atoms has been established in recent years but the quantitative understanding is still largely based on computations because of a persistent lack of suitable experimental data. We herein report a comprehensive computational and experimental study of the compensation of London dispersion in proton-bound dimer
近年来,伦敦分散体对于少于200个原子的分子的结构和稳定性的重要性已经确立,但由于持续缺乏合适的实验数据,对定量的理解仍主要基于计算。我们在此报告了质子结合的二聚体解离中伦敦色散补偿的综合计算和实验研究,结果表明,极性和非极性非质子溶剂中的总补偿在很大范围内都具有很大的不变性。此外,我们发现在典型的实验温度下,溶剂补偿(约40%至80%)比气相补偿(约0%至40%)在很大程度上占优势。
