共振二色二光子电离用于研究 NaNH3 的第一电子激发态，作为尺寸选择的溶剂化碱金属原子系统（碱·溶剂）的第一个例子。观察到的光谱显示出复杂的振动和旋转结构。在 12 220 cm−1 (1.52 eV) 处发现了 0-0 跃迁，与最近的理论计算非常吻合。随着激光功率的增加，可以看到分子的离子碎片，这表明研究此类模型系统中电荷转移过程动力学的可能新途径。
Resonant two color two photon ionization is used to investigate the first electronically excited state of NaNH3 as a first example of size selected, solvated alkali metal atoms systems (alkali⋅solventn). The observed spectrum shows a complex vibrational and rotational structure. The 0‐0 transition is found at 12 220 cm−1 (1.52 eV), in good agreement with recent theoretical calculations. With increasing laser power ionic fragments of the molecule are seen, indicating possible new avenues to study the dynamics of charge transfer processes in this type of model system.
