Intermolecular bond formations among Pt atoms in oligomers of Pt^II complexes are induced by photo‐irradiation. Femtosecond time‐resolved absorption measurements for aqueous solutions of K₂[Pt(CN)₄] recorded clear oscillations of transient absorption in the first few picoseconds with complex dynamics. The oscillations arise from the Pt−Pt stretch motions of the S₁ trimer and S₁ tetramer. The analysis of the oscillations provides clear assignments of the oligomers, as described by M. Iwamura, T. Tahara et al. their Research Article (DOI: 10.1002/anie.202011813).

激发态下分子间键形成后铂配合物低聚物的相干振动和飞秒动力学

Pt ^II配合物的低聚物中Pt原子之间的分子间键形成是通过光辐射诱导的。飞秒时间分辨的K ₂ [Pt（CN）₄ ]水溶液的吸收测量结果显示，在最初的几皮秒内，具有复杂动力学的瞬态吸收明显振荡。振荡是由S ₁三聚体和S ₁四聚体的Pt-Pt拉伸运动引起的。如M.Iwamura，T.Tahara等人所述，对振荡的分析提供了低聚物的明确分配。他们的研究文章（DOI：10.1002 / anie.202011813）。
