Solute triplet formation is observed in solutions of naphthalene in iso-propanol but not in those of camphorquinone. The cnmphorquinone triplet is formed if naphthalene is also present in the solutions. It is postulated that the efficiency of formation of the camphorquinone triplet depends upon the

โฆ Synopsis
Evolution of the absorption spectra due to uannent spec~cs produced by rhc pulse rrdrolysu of biphcnyl, pyrene, diphenylamine. and naphthalcne in cyclohcuane was measured over 50 ps to 3 ns. The mitial(50 ps) yield of triplet is only B small fraction of the ytrld (G -0.3) at 3 ns.
