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 K 2 [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 S 1 trimer and S 1 tetramer. Analysis of the oscillations provides clear assignments of the oligomers, as described by M. Iwamura, T. Tahara, and co‐workers in their Research Article on page 23154.
