  "term": "Experimental absorbance",
  "field": "Chemistry",
  "definition": "The decadic absorbance as measured, without correction for losses other than absorption, so reflection at cell windows, scattering and luminescence all add to it. It is calculated as the base-10 logarithm of the ratio of incident to transmitted radiant power and has no unit. Internal absorbance is the corresponding value after correction for these other processes.",
