  "term": "Radius of gyration",
  "field": "Chemistry",
  "definition": "A measure of the average size of a polymer coil in solution or in the melt, representing the root-mean-square distance of the polymer segments from its center of mass. It provides insight into the spatial extent and conformation of a macromolecule. This value can be determined experimentally using light scattering or neutron scattering techniques.",
