Attenuated total reflection infrared spectroscopy

  "id": "MLC-T-CHM-000930",
  "term": "Attenuated total reflection infrared spectroscopy",
  "field": "Chemistry",
  "definition": "A spectroscopic technique that uses attenuated total reflection to obtain infrared spectra of samples, particularly solids, liquids, and pastes, without extensive sample preparation. An infrared beam passes through a high refractive index crystal, and the evanescent wave interacts with the sample in contact with the crystal surface. This method provides surface-sensitive vibrational information.",
