attenuated total reflectance

[ə′ten·yə‚wād·əd ′tōd·əl ri′flek·təns]
(spectroscopy)
A method of spectrophotometric analysis based on the reflection of energy at the interface of two media which have different refractive indices and are in optical contact with each other. Abbreviated ATR. Also known as frustrated internal reflectance; internal reflectance spectroscopy.

Attenuated total reflectance (ATR) infrared spectroscopy makes it possible to rapidly monitor subtle compositional changes in tomatoes and helps determine, non-invasively and in real time, the effects that different processing methods might have on these compounds.
Other IR methods, such as attenuated total reflectance (ATR) and photoacoustic methods, can provide IR spectra of thick materials, because they penetrate a very thin layer at the surface of a sample.
It is also the case that, whereas the previous two editions were comprised of only four separate sub-libraries, covering the transmission and pyrolysate spectra of both rubber and plastic materials, another major improvement for this edition has been the incorporation of an additional, comprehensive library produced using a single bounce attenuated total reflectance (ATR) accessory.
7) used four sampling techniques: transmission spectroscopy, diffuse reflectance, attenuated total reflectance (ATR), and specular reflectance.
