  "term": "End-to-end distance",
  "field": "Chemistry",
  "definition": "The spatial distance between the two terminal atoms or segments of a polymer chain. This parameter provides a measure of the overall size and conformation of a polymer molecule in solution or in a melt. For a random coil polymer, the mean-square end-to-end distance is proportional to the number of statistical segments in the chain.",
