In this paper, it is noted that 3,3'-deuteration has no measurable effect on k/sub nr/; these are positions of low electron density as judged by the fact that base-catalyzed /sup 1/H//sup 2/H exchange occurs readily on the metal complex at these positions. There is no evidence for exchange at the 6,6'-positions. Second, the results obtained agree qualitatively with /sup 1/H NMR data. Measured chemical shifts show the lowest electron density at the 3,3'-positions with increased electron density at the 6,6'-positions. For the metal complex, the order of increasing chemical shift is 5,5' < 6,6' < 4,4' < 3,3' while for the free ligand the order is 5,5' < 4,4' < 3,3' < 6,6'.
