  "id": "MLC-T-CHM-006376",
  "term": "Kohlrausch-Williams-Watts equation",
  "field": "Chemistry",
  "definition": "An empirical equation used to describe the non-exponential relaxation behavior observed in many disordered systems, including polymers and glasses. It models the decay of a physical quantity, such as stress or polarization, over time with a stretched exponential function. The equation is characterized by a relaxation time and a stretching exponent.",
