“…Quenching Rate Constants. In a thoroughly deaerated aqueous solution with no quencher, [Pt 2 (pop) 4 ] 4- showed an emission decay lifetime of 9.7 μs, in good agreement with the literature ,, value. The lifetime was shortened to 8−9 μs in acidic media, but on addition of Cl - , no change was observed within the experimental error of ±0.1 μs.…”

“…Stern − Volmer Quenching of 3 Pt 2 (pop) 4 4- by Ni(II) Complexes. In a thoroughly degassed solution, and in the absence of any quencher, the lifetime of a fresh solution of a fresh sample of Pt 2 (pop) 4 4- was found to be about 9 μs, which is in good agreement with literature. The addition to 3.0 mL of Pt 2 (pop) 4 4- solution of several successive 5−20 μL aliquots of Ni(II)-complex (∼ 1 × 10 -3 M in 0.01 M HClO 4 ) was found to cause a steady decrease in the measured lifetime. Stern−Volmer analysis of the lifetime data gave linear plots which provided values for the second-order rate constants, k q , for the quenching of the excited state of Pt 2 (pop) 4 4- by each of the ten Ni(II) complexes.…”

“…Temperature dependence of phosphorescence decay is accompanied by a pressure dependence [124]. 3 dσ*pσ lifetimes of Rh(TMB) and Ir(pz)(CO)(cod) increase with increasing pressure, with activation volumes of +4.6 and +2.8 cm 3 mol -1 in MeCN.…”

“…3 dσ*pσ lifetimes of Rh(TMB) and Ir(pz)(CO)(cod) increase with increasing pressure, with activation volumes of +4.6 and +2.8 cm 3 mol -1 in MeCN. These increases were interpreted [124] as evidence for a strong-coupling [120] decay mechanism whereby the excited molecules undergo expansive distortion to achieve a crossing point with the groundstate potential energy surface. On the other hand, very weak pressure dependence and small negative volumes of activation were determined [124] in MeCN for Pt(pop) (-0.2 cm 3 mol -1 ) and…”
