Fourier transform IR
spectroscopy (FT-IR):
An infrared
spectroscopy technique in which the analyte
is exposed an infrared photon
beam containing many photon
wavelengths,
and the data recorded. The process is repeated multiple times,
each with a different set of infrared photon
wavelengths.
The resulting data is combined and treated with a mathematical
process called a Fourier transform to produce the infrared
spectrum.
