Well resolved ESR were analyzed on the basis of HMO calcns. In the case of the 1,10-phenanthrolines there are 2 LUMOs available to accommodate the addnl. electron; a comparison of the spin distributions demonstrates that, in contrast to earlier assumptions, it is the 5b1 orbital that is singly occupied.
