介绍了一种新的数据分析方法，它可以应用于瞬态振动和频产生光谱，揭示隐藏的分子动力学的电荷转移在分子异质结界面。在验证该方法后，我们用它来提取有机半导体/金属界面的分子动力学，否则由电子动力学主导。这样的能力可以推进的界面电荷转移动力学中的分子的作用的理解。
We introduce a new data analysis method, which can be applied to transient vibrational sum-frequency generation spectroscopy to reveal hidden molecular dynamics of charge transfer at molecular heterojunction interfaces. After validating the method, we used it to extract molecular dynamics at organic semiconductor/metal interfaces, which was otherwise dominated by electronic dynamics. Such an ability can advance the understanding of the roles of molecules in interfacial charge transfer dynamics.
