Attenuated Total Reflectance (ATR) And Reflection Absorption Infrared (RAMS) Spectroscopic Analysis Of Thin Films

Attenuated total reflectance infrared spectroscopic (ATR-IR) analysis (also termed in ternal reflectance spectroscopy or Ins) of thin films coated on an internal reflectance element (IRE) should be considered a viable alternative to the reflection absorption infra-red spectroscopic (RAIRS) method, where thin films are coated an mirror surfaces, preliminary results have shown that reasonable, if not superior, spectra can be obtained for films as thin as 25 A (approximately a monolayer) coated on a germanium crystal.
