We present theoretical analyses of two different aspects ofthe time dependence of the fluorescence Stokes shift in polar liquids. We show that a small deviation from the Debye form for the dielectric relaxation of the solvent can strongly influence the time evolution of the Stokes shift. Using the D
The pulse recovery method is applied to the triplet states of naphthalene, quinoxalene, and tetramethylpyrazine 03iP) in durene and biphenyi host crystals for 1.25% d Td 4.23%. Temperature dependen~es of the spin-lattice relaxation rates are characteristic of Raman and direct processes.
