摘要:
在本工作中,我们提出了一种半经典方法,利用OpenMM分子动力学模拟,在水溶液中建模分子间库仑电子捕获(ICEC)。我们研究了在水中的过量电子在阳离子(Fe³+)存在下的行为,重点考察电子能量和阳离子浓度对ICEC量子产率的影响。我们的模拟结果显示,随着浓度和初始电子能量的增加,ICEC量子产率接近于1,而在较低浓度下,由于电子在到达阳离子前的能量损失,量子产率会下降。
英文摘要:
In this work, we present a semiclassical approach to model Intermolecular Coulombic Electron Capture (ICEC) in aqueous solutions using molecular dynamics simulations with OpenMM. We investigate the behavior of an excess electron in the presence of cations (Fe$^{3+}$) in water, focusing on the influence of electron energy and cation concentration on the ICEC quantum yield. Our simulations reveal that the ICEC quantum yield approaches unity at higher concentrations and initial electron energies, while it decreases at lower concentrations due to electron energy loss before reaching the cation.
