摘要:

我们研究了三原子氘分子D_3的2p^2A^"_2和3d^2E^”态的振动能。实验是使用一个快速中性束光电离光谱仪最近开发的弗莱堡。采用了两束脉冲染料激光器的耗尽型光学双共振方案。D_3的2p^2A^"_2态的振动频率的测量值与H_3的振动频率和从头计算势能面的理论值进行了比较。这些数据给洞察价电子和离子核之间的耦合的重要性。

英文摘要:

We investigated the vibrational energies in the 2p^2A^"_2 and 3d^2E^" states of the triatomic deuterium molecule D_3. The experiments were performed using a fast neutral beam photoionization spectrometer recently developed at Freiburg. A depletion type optical double-resonance scheme using two pulsed dye lasers was applied. The measured vibrational frequencies of the 2p^2A^"_2 state of D_3 are compared to those of H_3 and to theoretical values calculated from an ab initio potential energy surface. The data give insight into the importance of the coupling between the valence electron and the ion core.
