(a) Absorption spectrum of 1 (red line) obtained from oxygenation of [(tmpa)CuI(CH3CN)]+ (black line) at −80 °C in acetone. (b) Transient difference absorption spectra of 1 in acetone at −80 °C measured at the indicated delay times after 490 nm femto-second laser excitation (2 mJ/pulse and fwhm = 130 fs). Overlaid in green is a simulated spectrum for 1, generated by subtraction of the red spectrum from the black spectrum shown in (a).
