论文摘要
通过两光子过渡（Rabbitt）的干扰重建Attsond跳动是一种强大的光电子光谱，可直接访问目标的内部动力学。它越来越多地应用于分子系统，但是迄今为止缺乏一般的分子频谱理论，迄今为止缺乏分子光谱的理论。我们表明，在相当普遍的假设下，分子中的Rabbitt光谱可以表示为振动互相关函数和两电子光电子矩阵元素的卷积。我们将一般表达方式专门针对常见的特殊情况。我们希望我们的理论能够在大多数中型分子中对分子rabbitt光谱进行准确的建模和解释。
Reconstruction of attosecond beating by interference of two-photon transitions (RABBITT) is a powerful photoelectron spectroscopy, offering direct access to internal dynamics of the target. It is being increasingly applied to molecular systems, but a general, computationally tractable theory of RABBITT spectra in molecules has so far been lacking. We show that under quite general assumptions, RABBITT spectra in molecules can be expressed as a convolution of the vibronic cross-correlation functions and two-electron photoionization matrix elements. We specialize the general expressions to the commonly-encountered special cases. We expect our theory to enable accurate modeling and interpretation of molecular RABBITT spectra in most medium-sized molecules.
