Fourier-transform infrared spectroscopy Insights

What is Fourier-transform infrared spectroscopy?

Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range. This provides information about the chemical bonds and composition of a material. It is commonly used for identifying materials, quality control, and analyzing complex mixtures.

Fourier-transform infrared spectroscopy Complementary Technologies

Raman spectroscopy

Raman spectroscopy is complementary to FTIR, as it probes vibrational modes that may be weakly or not at all active in the infrared region, and vice-versa. This is due to different selection rules based on polarizability changes (Raman) vs. dipole moment changes (FTIR).

gas chromatography

Gas chromatography (GC) separates volatile compounds, and FTIR can be used as a detector (GC-FTIR) to identify the separated compounds based on their infrared spectra. The two techniques are therefore complementary.
