Abstract

The wavelength-dependent diffuse transmission through a monodisperse colloidal suspension is shown to provide wave-vector-dependent information about the colloid structure factor. Experiments demonstrate that the spectral fingerprint can be used to distinguish quantitatively samples of different particle sizes, different concentrations, and different interparticle interactions.
