For [Ru(bpy),] (PF,),, 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 k 0.5 cm-' at B= 6 T. It is concluded that at B equal zero, the parent terms of the

โฆ Synopsis
The positions and intensities of the electronic origins in [Zn(bpy),] ( C104)*: Ru( II) are strongly dependent on the orientation of an applied magnetic field within the metal-ligand plane. Spectra can be calculated by a mode1 in which the lowest-energy charge-transfer excitations involve an individual metal-l&and subunit. The mode1 can also reproduce all the significant features of the spectra reported for [ Ru (bpy ) s ] (PF, ) *.

The last sentence of the second paragraph on page 125 (right column) is incorrect and misleading. It should read: Consequently, also these experimental results are at variance with the assumed electron localization but are explainable by a delocalized model with one chromophore exhibiting two low-l
Zeeman measurements made near 178 15 cm-' at 4.2 and 1.4 K on a Ru( bpy),( PF6)Z single crystal, in both absorption and luminescence, are presented.
