Ru(bpy)32+ quenched by Co(NO2)63– at conc. (2-7) x 10–4 mol L–1
Solvent : H2O, ~21ºC, ionic strength 0 (calc'd)

kq = ~9 x 109(L mol–1 s–1)

Mechanism: oxidative electron transfer
Experimental methods: steady state irradiation, luminescence
Lifetime in the absence of quencher, air free = 0.60 micro sec. (laser flash, luminescence, multiple shot with signal averaging)
