论文摘要
我们开发了H $ _2^+$分子的两个新型模型及其同位素，从中，我们可以通过机械和半传统评估量子，分子是否在第一个激发电子状态下与该场抗抗抗。这两个模型的结果允许我们即使对于拥有永久偶极矩的HD $^+$同位素，即使对于HD $^+$同位素也是如此。由于种群通过圆锥形交叉交换，分子以垂直于场和地面电子状态的场极化的角度分离。初始状态的量子机械分散足以引起完全解离。我们得出的结论是，这些分子在激发态下通过在强场下的键粘贴在激发态中的稳定性极不可能。
We develop two novel models of the H$_2^+$ molecule and its isotopes from which we assess quantum-mechanically and semi-classically whether the molecule anti-aligns with the field in the first excited electronic state. The results from both models allow us to predict anti-alignment dynamics even for the HD$^+$ isotope, which possesses a permanent dipole moment. The molecule dissociates at angles perpendicular to the field polarization in both the excited and the ground electronic state, as the population is exchanged through a conical intersection. The quantum mechanical dispersion of the initial state is sufficient to cause full dissociation. We conclude that the stabilization of these molecules in the excited state through bond-hardening under a strong field is highly unlikely.
