研究了反式[ptcl2 (en) 2](clo4) 2上的电子-声子相互作用，其中en表示乙二胺。在该体系中，铂的电子态被卤素离子的呼吸模式直接调制，并发生强烈的电子-声子相互作用。发光光谱具有由20多个系列声子边带叠加而成的类高斯线形。考虑到卤素呼吸模式，可以很好地解释光谱的形状。估计耦合强度（Haung-Rhys因子）为9.52。
Electron-phonon interaction is studied on the trans-[PtCl 2 (en) 2 ](ClO 4 ) 2 , where en denotes ethylenediamine. The electronic states of platinum in this system are directly modulated by the breathing mode of halogen ions and strong electron-phonon interaction occurs. Luminescence spectrum has a Gaussian-like lineshape which is superimposed by phonon side bands of more than 20 series. The shape of the spectrum is well interpreted by taking account of halogen breathing mode. The estimated coupling strength (Haung-Rhys factor) is 9.52.
