Excess scattering

  "id": "MLC-T-CHM-004164",
  "term": "Excess scattering",
  "field": "Chemistry",
  "definition": "The portion of scattered light intensity from a polymer solution that is attributable solely to the presence of the dissolved macromolecules, after subtracting the scattering from the pure solvent. This phenomenon is observed in light scattering experiments and is directly related to the concentration, size, and shape of the polymer molecules. It forms the basis for determining molecular weight and dimensions.",
