Summary of mechanism and kinetic rates from TAS measurements with suspensions of NCNCNx (1–5 mg mL–1), NiP (up to 24 μM), and 4-MBA (10 mM) in an aqueous KPi solution (0.02 M, pH 4.5, 25 °C). Representative lifetimes, calculated using 3 μs as the initial time, are indicated near reaction arrows. Recombination reactions are indicated by dashed gray arrows.
