Zeeman splittings of the two lowest excited states of [Ru(bpy)₃](PF₆)₂

Abstract

For [Ru(bpy)₄](PF₆)₂ the splittings of the two lowest excited electronic states could be measured under magnetic fields (Zeeman effect ). The splittings of both states increase with the magnetic-field strength to 3 ± 0.5 cm⁻¹ at B= 6 T. It is concluded that at B equal zero, the parent terms of these two states cannot be classified as originating from a situation in which one electron is localized on one ligand.
