Multiple reflection attenuated total reflection FT-IR accessory allows for protein analysis of strongly IR-absorbing samples, such as aqueous solutions.

Clays, like kaolinite and smectite, are hygroscopic and it is well known that the adsorbed water can be driven off at elevated temperatures. At very low temperatures, in addition to the typical band narrowing and shifting, changes in the O-H bond vibrational modes of clays have also been observed.
