Dynamic Stark-induced degenerate state (DSIDS) is essential to generate electronic coherent angular momentum to identify molecular chirality. We previously derived DSIDS for phenylalanine enantiomers in the independent interaction model (IIM), in which two linearly polarized nonresonant UV lasers independently interact with relevant two electronic excited states. We present a numerical method to derive DSIDS beyond IIM. Here, both lasers interact with both excited states, and laser input parameters are determined for DSIDS located at the center of the excited states. The numerical results reasonably agree with those calculated in the IIM, which elucidate the validity of DSIDS in the IIM.

动态斯塔克诱导的简并状态（DSIDS）对于产生电子相干角动量以识别分子手性至关重要。我们先前在独立相互作用模型（IIM）中获得了苯丙氨酸对映体的DSIDS，其中两个线性偏振的非共振UV激光器独立地与相关的两个电子激发态相互作用。我们提出了一种数值方法来推导超越IIM的DSIDS。在此，两个激光器都与两个激发态相互作用，并确定位于激发态中心的DSIDS的激光器输入参数。数值结果与IIM中计算得出的结果基本吻合，从而阐明了DSIM在IIM中的有效性。
