attenuated total reflection spectroscopy

synonyms: frustrated total internal reflection spectroscopy, internal reflection spectroscopy (IRS)
https://doi.org/10.1351/goldbook.08573
Measurement method of vibrational spectroscopy based on internal reflection from an absorbing material at angles of incidence at or above the critical angle (attenuated total reflection).
Note:
Attenuated total reflection occurs where the material absorbs. The resulting spectrum resembles an absorption spectrum of the sample.
