摘要：
The temperature dependence for the exchange of bis(2-ethylhexyl)phosphoric acid with the copper(II) complex of this acid has been studied in trichloroethylene using nmr line-broadening techniques. The chemical-exchange rate constant is 8.8 × 106 sec-1 at 298°K (assuming two sites for relaxation of the acid hydrogen). The scalar coupling constant is 1.8 × 106 Hz. The spin-lattice relaxation time for the unpaired electron of the copper(II) complex is 4.9 × 10-7 sec. © 1969, American Chemical Society. All rights reserved.
