What does FTIR stand for?

• A. Frequency Transform Infrared
• B. Fourier Transform Infrared
• C. Fourier Transform Ultraviolet
• D. Fourier-Transform Infrared Radiation

Answer: (B)

FTIR stands for Fourier Transform Infrared (spectroscopy). The Fourier Transform is the mathematical process that converts the interferogram collected by an infrared spectrometer into a spectrum, enabling precise measurement of how a sample absorbs infrared light. The infrared portion refers to the region of the spectrum used to excite molecular vibrations, which reveals functional groups and structural information about the sample. Some write it as Fourier-transform infrared spectroscopy, which means the same thing. The other options aren’t correct because they use the wrong transform type (Frequency Transform), point to the ultraviolet region instead of infrared, or append Radiation to infrared in a way that isn’t the standard name for the technique.
