Fl fluctuating hydrodynamics is generalized to study the effect of fractional time derivatives on the light-scattering spectrum of a suspension in a viscoelastic solvent under an external density gradient, and it is found that the ratio of the former to the latter may be positive and up to two orders of magnitude for both types of vis coelasticity.
