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.
