  "term": "Absorption spectrum",
  "field": "Chemistry",
  "definition": "A plot of the amount of light absorbed by a substance as a function of wavelength or frequency. It reveals the characteristic wavelengths at which a substance absorbs electromagnetic radiation, corresponding to electronic or vibrational transitions within its molecules. This spectrum is unique for each compound and is used for identification and quantitative analysis.",
