摘要：

A numerical method is presented to recover the excimer formation rate coefficient from the experimental monomer and excimer decay curves. This method was applied to study pyrene monomer-excimer kinetics in cyclohexanol from 25-degrees-C up to 85-degrees-C. We observed that the time evolution of the rate coefficient deviates from the Smoluchowski equation, showing a minimum at high temperatures and concentrations, when the reversibility effects are more pronounced.
