Triplet State of Triphenylamine
Nature, 1969Two transient species with absorption peaks at 5300 and 6100 A have been observed in de-oxygenated solutions of triphenylamine by a flash photolysis technique1,2. The major product at room temperature is said to have been the 6100 A compound, and this was considered to be an “intermediate” from which N-phenyl carbazole was formed in the presence of ...

The Journal of Chemical Physics, 1963
The sensitization of biacetyl fluorescence and phosphorescence using benzene as donor has been studied at 25°C in aerated and de-aerated hexane solutions. Electronic energy transfer from the lowest excited singlet state of benzene to biacetyl producing either the first or second excited singlet state of biacetyl proceeds with a rate constant (3.3×1010 ...

Triplet State Excitation Phenomena
1976The nature of spin-orbital interaction in molecules permits the study of triplet-state properties as a means of orbital characterization of the excited state. Electronic transitions in aza-N-heteroaromatics, in pyrrolo-heteroaromatics, and in hydrocarbon aromatics, e.g., can thus be classified into three separate groups according to the nature of spin ...
