Quenching primary donor triplet states

Primary step I The relative efficiencies of biacetyl and butene-2 in the quenching of reaction I were found to be not far from unity in the case of the ketones studied consequently, primary process I occurred from the high vibrational levels of the triplet state, possessing sufficient energy to induce efficiently the isomerization of butene-2. The efficiency of energy transfer to cw-butene-2 compared with that to biacetyl, measured in terms of reaction I, was found to be in the following order 2-pentanone > 2-butanone > acetone. It is possible that this order reflects the facility with which the vibrational energy of the donors may be made available to... [Pg.352]

Quenching the triplet-excited states of the fullerenes by the electron donors occurs efficiently in polar solvents like benzonitrile. The mechanism is a primary electron transfer [Eq. (1) [120,125,133,139,148,154-162],... [Pg.658]
