Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR ... At its core, FTIR involves the collection of high-spectral-resolution data over a wide spectral range.

Fourier Transform Infrared Spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption, emission, photoconductivity or Raman scattering of a solid, liquid or gas.

The most common type of IR spectrometer is the Fourier Transform Infrared (FTIR) spectrometer, which uses an interferometer to collect high-spectral-resolution data over a wide spectral range. Sample ...
