What is FT IR? - Northwestern University
www.nuance.northwestern.eduInfrared (IR) spectroscopy is a chemical analytical technique, which measures the infrared intensity versus wavelength (wavenumber) of light. Based upon the wavenumber, infrared light can be categorized as far infrared (4 ~ 400cm‐1), mid infrared (400 ~ 4,000cm‐1) and near

The remaining polymer is next dissolved and cast as a film on a sodium chloride plate. The absorbance of the carbon disulfide extract and the thin film are then measured over the range of the mid-IR frequencies using an infrared specrophotometer.
