U. 25. Absorption and fluorescence spectra of Pyþ and Oxþ in zeolite L, measured in an aqueous dispersion. The different spectral overlap regions are shaded. by the extinction coefficient ej ð" v Þ of the acceptor as a function of the wave number v" (it is usually expressed in units of cm3/M). 25. It is difficult to measure the oscillator strengths of molecules embedded in a matrix. Despite this, good values of Jij can be determined as a function of the temperature. A procedure we have used to extract the information from excitation spectra was to set the maximum of the excitation spectrum measured at room temperature equal to the extinction coefficient at the absorption maximum in solution.

30. Diffusion of dye molecules in the channels of zeolite L. Idealized initial state of a channel and state after diffusion has occurred for some time. L channels. 30, at the beginning of the experiment. Immediately after all dye molecules have entered the zeolite channels, the maximum energy transfer is observed because the donor-to-acceptor distance is short. The donor-toacceptor distance increases, and hence the energy-transfer rate decreases, when the molecules diffuse deeper into the channels.
