This paper examines relationships between the quasielastic light scattering spectrum S(q, t) and the distribution functions for particle displacements over various times. For dilute probes in a complex, non-scattering fluid, S(q, t) is determined by the even moments of the one-particle displacement distribution function P(X, t). For concentrated scattering… CONTINUE READING
