Unperturbed conformational state

  "id": "MLC-T-CHM-012446",
  "term": "Unperturbed conformational state",
  "field": "Chemistry",
  "definition": "The average conformation of a polymer chain in a theta solvent, where long-range interactions between segments of the chain are effectively screened. In this state, the polymer chain behaves as an ideal random coil, and its dimensions are determined solely by short-range interactions and bond rotations. This state is achieved at the theta temperature.",
