Stopped-flow UV-vis spectra of oxidation of 0.7 mM Cu(I)-HPAz by 1 eq Na2IrCl6 at pH 6.5 in 50 mM phosphate buffer and 100 mM NaCl. (A) Spectral changes in first 10 s of reaction. (B) Simulated spectra of individual species as determined by the SpecFit program. (C) Time-dependent transitions of Na2IrCl6, Blue Cu(II)-HPAz and Green Cu(II)-HPAz, as simulated by the SpecFit program.
