Dynamics of macromolecular chains. IV. Quenching and fluorescence polarization studies of polystyrene in solution

Combined measurements of quenching and fluorescence polarization corroborate the results previously obtained by the polarized fluorescence anisotropy decay technique and, more especially, confirm the form of the proposed orientation autocorrelation function. The use of this method to determine the mean relaxation time of the relaxation time distribution is also explained.
