The triplet lifetime of aromatic hydrocarbons in liquid solution is relativc:jr short compared with the lifetime in a rigid solution. Until now this difference has been exphined by an impurity quenching mechanism. An alternative explanation is given, assuming quenching of a triplet molecule by B sin
## Abstract Fluorescence rise and decay processes were measured and rate parameters were determined for the pyreneβtriβ__n__βbutylamine and pyreneβN,Nβdiethylaniline exciplex system in various solvents. An additional activation energy over that for the diffusional motion appears necessary for both
