Cr(bpy)33+ quenched by cis-Co(en)2(NCS)2+ at conc. (1-5) x 10–4 mol L–1
Solvent : H2O, 0.1 mol/L H2SO4, 22ºC

kq = 3.9 x 108(L mol–1 s–1)

Mechanism: energy transfer
Experimental methods: steady state irradiation, luminescence
Lifetime in the absence of quencher, air saturated = 38 micro sec. (laser flash, luminescence, multiple shot with signal averaging)
