  "id": "MLC-T-CHM-007466",
  "term": "Molar absorption coefficient",
  "field": "Chemistry",
  "definition": "A quantitative measure of how strongly a chemical species absorbs light at a particular wavelength. It represents the absorbance of a solution with a concentration of one mole per liter in a path length of one centimeter. This coefficient, often denoted by epsilon (ε), is expressed in units of L mol⁻¹ cm⁻¹.",
