Conformational enthalpy

  "id": "MLC-T-CHM-002416",
  "term": "Conformational enthalpy",
  "field": "Chemistry",
  "definition": "The change in enthalpy associated with a transition between different conformational states of a polymer chain. This energy difference arises from changes in intramolecular interactions, such as bond rotation and non-bonded forces, as the polymer backbone adopts a new spatial arrangement. The value is determined experimentally using techniques like calorimetry or spectroscopy and is expressed in units of energy per mole, such as kilojoules per mole (kJ/mol).",
