Dependencies of the rate constants for peroxynitrite formation (k_form) measured at 315 nm upon oxygen concentration. Circles are for alkaline solution (pH 12.7), 0.15 mM N₂O₃^2–, the dashed line is presented as a visual aid only; squares are for neutral solution (pH 7), 0.6 mM HN₂O₃^–, the solid line gives a linear fit with intercept fixed at 0.
