液态水中电场起伏的统计特性

The statistics of electric field fluctuations in liquid water

Bernhard Reischl, Jürgen Köfinger, Christoph Dellago

摘要:

电场波动在液态水的离解反应中起着重要作用,并决定了其振动光谱响应。在这里,我们使用分子动力学计算机模拟研究了液态水中电场的统计特性,特别关注驱动解离的强而罕见的场。我们的模拟表明,重要的贡献,电场作用在OH键干水分子小于7埃。长期贡献所起的作用很小。

英文摘要:

Electric field fluctuations play a major role in dissociation reactions in liquid water and determine its vibrational spectroscopic response. Here, we study the statistics of electric fields in liquid water using molecular dynamics computer simulations with a particular focus on the strong but rare fields that drive dissociation. Our simulations indicate that the important contributions to the electric field acting on OH bonds stem from water molecules less than 7 Å away. Long-ranged contributions play a minor role.
