  "id": "MLC-T-CHM-000077",
  "term": "Absorption index",
  "field": "Chemistry",
  "definition": "The imaginary component of the complex refractive index, representing the attenuation of electromagnetic radiation as it propagates through a medium. It quantifies how strongly a material absorbs light at a particular wavelength. This dimensionless quantity is directly related to the absorption coefficient of the material.",
