Such FTIR methods have long been used for plastics, and became extended for composite materials in 2018, when the method was introduced by Krauklis, Gagani and Echtermeyer. [20] FTIR method uses the maxima of the absorbance band at about 5,200 cm−1 which correlates with the true water content in the material.
Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect.

The refractive index of water at 20 °C for visible light is 1.33. [1] The refractive index of normal ice is 1.31 (from List of refractive indices).In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength.
In the United States state of Kentucky, a moist county is a county the regulations in force of which are between those of a "dry county" (in which the sale of alcoholic beverages is prohibited) and a "wet county" (in which alcohol is sold). The term is typically used for any county that allows alcohol to be sold in certain situations but has ...
ATR-FTIR is also used as a tool in pharmacological research to investigate protein/pharmaceutical interactions in detail. Water-soluble proteins to be investigated require Polyhistidine-tags , allowing the macromolecule to be anchored to a lipid bilayer, which is attached to a Germanium crystal or other suitable optical media.
