Fig. 2. Evolution of the electronic absorption spectra of a solution of [1]Cl (top) and [2](PF6) (bottom) in demi-water upon green light irradiation under argon (λ = 530 nm, Δλ1/2 = 25 nm, 3.02 mW, 2.1 × 10–8 einstein per s). Time: 0 min (red curve) to 120 min (black curve, a) or 160 min (black curve, b). Conditions [Ru]0 = 7.5 × 10–5 (a), 7.8 × 10–5 (b), irradiated volume was 3.0 mL at 298 K.
