M. Iida et al., INTERACTIONS OF SOME CATIONIC COBALT(III) COMPLEXES WITH ANIONS STUDIED BY THE CO-59 NMR CHEMICAL-SHIFTS, Bulletin of the Chemical Society of Japan, 66(8), 1993, pp. 2398-2401
The NMR peak of Co-59(III) cationic complexes shifts upfield upon inte
racting with anions when the interaction is mainly electrostatic; it s
hifts downfield when the hydrophobic interaction acts additively with
the electrostatic interaction. These trends are enhanced in micellar s
olution systems.
