Abstract

It is argued that the decrease of fluorescence depolarization observed when diphenylanthracene is dissolved in poly(γ‐benzyl‐L‐glutamate) or polystyrene solution is due to short‐range interactions, and not to long‐range hydrodynamic interactions. Estimates of the hydrodynamic effect are given. Rough estimates of the effect to be expected on the short‐range hypothesis are in qualitative agreement with experiment.
