We characterize attosecond transient absorption spectroscopy (ATAS) in molecules with coupled nuclear and electronic dynamics in the vicinity of a conical intersection between adiabatic potential energy surfaces. With respect to ATAS, the nonadiabatic vibronic coupling strength can be divided into weak, intermediate, and strong, and the characteristics of spectra belonging to each of these domains are discussed. The results can guide the analysis of ATAS experiments in molecules with conical intersections.
我们在紧邻绝热势能面交叉点的位置，对分子中耦合的核和电子动力学的阿秒瞬态吸收光谱（ATAS）进行了特征描述。就 ATAS 而言，非绝热振子耦合强度可以分为弱、中、强三种，并且讨论了属于这三个区域的光谱特征。这些结果可以指导在具有交叉点的分子中进行 ATAS 实验的分析。
