โœฆ Synopsis

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. Most significantly, no effect is seen with B 11 c, but substantial shifts are seen with E I c. These measurements are in direct conflict with the interpretation of a body of recent work purporting to determine the electronic structure of the Ru(bpy):+ (RBY) moiety by a study of the temperature dependence of the luminescence of a number of concentrated salts of RBY. The anomalous dependence on the relative orientation of B and the detecting polarization vector E is qualitatively similar to measurements on dilute RBY systems. The nature of the electronic structure of the RBY luminophore below 10 K is discussed.

Luminescence decay kinetics of the title series, measured after quasi-steady-state excitation, are found to be first order under all conditions. The decay rates of the X= 1 and 2 partially deuterated complexes are approximately evenly spaced between the x=0 and X= 3 values. Luminescence profiles are
