Popis:	Fluorescence, photoacoustic calorimetry, and picosecond optical calorimetry studies on the rigid donor-spacer-acceptor (DSA) molecule, 1, in alkane and ether solvents are reported. The charge transfer (CT) state of 1 is formed with unit quantum efficiency and decays by numerous processes. Charge recombination from the CT state generates both the ground state and the triplet state of the naphthalene chromophore. The quantum yield of triplet state formation decreases with an increase in the dielectric constant of the solvent. The CT state radiative, nonradiative internal conversion (CT→S 0 ), and nonradiative intersystem crossing (CT→T 1 ) rate constants are determined and are analyzed using semiclassical, single quantized mode, electron transfer theory
