  "term": "Rotational diffusion coefficient",
  "field": "Chemistry",
  "definition": "A measure of the rate at which a molecule reorients itself due to random thermal motions in a fluid. This coefficient quantifies the average angular displacement per unit time for a rotating particle. It is inversely proportional to the rotational friction coefficient and is often determined through techniques like dynamic light scattering or nuclear magnetic resonance spectroscopy.",
