The effects of molecular size, conjugation length, and competition with excimer formation on excited state intramolecular proton transfer (ESIPT) in conjugated polymers, in which the intramolecularly hydrogen-bonded moieties reside in the main chain, were examined. A large extent of T-electron deloc

Electron-transfer rates were determined in solvents of different polarity as a function of temperature and analyzed in terms of activation energies and pre-exponential factors. Both were found to depend on the polarity of the solvent. The solvent dependence of the pre-exponential factor is interpret
The effect of anharmonicity in the stretch and bend modes of benzene on the rate of energy flow from an excited CH stretch local mode is investigated using quasiclassical trajectories. Potentialenergy surfaces with varying degrees of anharmonicity are used in the calculations to determine which mode
