  "id": "MLC-T-CHM-002890",
  "term": "Decadic absorbance",
  "field": "Chemistry",
  "definition": "A measure of the attenuation of light as it passes through a sample, defined as the common logarithm (base 10) of the ratio of the incident radiant power to the transmitted radiant power. It is a dimensionless quantity and is directly proportional to the concentration of the absorbing species and the path length of the light. This is also known as absorbance.",
