Abstract
The dynamics of solvation of coumarin 480 guest molecule in supercages of a faujasite zeolite 13X is studied using picosecond time-resolved emission spectroscopy. The guest molecule exhibits a time-resolved Stokes shift in zeolite 13X. The decay of the response function, C(t), is nonexponential with the major components on a nanosecond timescale. The average solvation time is observed to be 8.13 ns. The nanosecond solvation is attributed to the self-motion of the probe solute and the motion of the sodium ions present in the zeolite host.
