This study leverages two-pulse femtosecond stimulated Raman spectroscopy (2FSRS) to characterize molecular systems with avoided crossings (ACs) and conical intersections (CIs) in their low-lying excited electronic states. By simulating 2FSRS spectra of microscopically inspired ACs and CIs models, we demonstrate that 2FSRS not only delivers valuable information on the molecular parameters characterizing ACs and CIs but also helps distinguish between these two systems.
本研究利用双脉冲飞秒受激拉曼光谱（2FSRS）来表征其低激发电子态中存在避免交叉（ACs）和锥形交叉（CIs）的分子体系。通过模拟微观启发的ACs和CIs模型的2FSRS光谱，我们证明2FSRS不仅能提供有关表征ACs和CIs的分子参数的有价值信息，还有助于区分这两种体系。
