Notes:
In a side-by-side comparison, the q dependence of the collective internal decay constant ∼(ΔΓ)∼qγ of linear polystyrene in good and theta solvents was determined using photon correlation spectroscopy. The results q2.9 and q3.9 for the theta and good solvents, respectively, correspond to relatively strong hydrodynamic interactions (nondraining) when excluded volume effects are minimal for the compact coil at theta and to relatively weak hydrodynamic interactions (partial draining) when excluded volume effects are manifest in the swollen coil in good solvent.
