The magnetic field effect on the intensity of delayed monomer fluorescence is different from the effect on delayed dimer fluorescence. It is concluded that delayed monomer and dimer fluorescence must stem from Wo different types of T-T annihilation process. Pola&ation of the magnetic fieldeffects ha
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
The use of magnetic field effects in delayed fluorescence (DF) and electrogenerated chemihrminescence (ECL) studies to obtain information about the involvement of triplet state species in reactions leading to the production of monomeric and dim&c (excimer or exciplex) excited states is described. In
