  "id": "MLC-T-CHM-011095",
  "term": "Specific absorption coefficient",
  "field": "Chemistry",
  "definition": "A measure of how strongly a substance absorbs light at a particular wavelength, normalized by its concentration and the path length of the light through the substance. It quantifies the intrinsic ability of a material to absorb radiation. This coefficient is typically expressed in units of L g⁻¹ cm⁻¹ or m² kg⁻¹.",
