2. Fourier-transform infrared spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Fourier-transform_infrared...

   Fourier transform infrared spectroscopy (FTIR) [1] 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-resolution spectral data over a wide spectral range.

3. Infrared spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Infrared_spectroscopy

   Fourier transform infrared (FTIR) spectroscopy is a measurement technique that allows one to record infrared spectra. Infrared light is guided through an interferometer and then through the sample (or vice versa). A moving mirror inside the apparatus alters the distribution of infrared light that passes through the interferometer.

4. Geology applications of Fourier transform infrared spectroscopy

   en.wikipedia.org/wiki/Geology_applications_of...

   An attenuated total reflectance (ATR)-FTIR spectrometer. Fourier transform infrared spectroscopy (FTIR) is a spectroscopic technique that has been used for analyzing the fundamental molecular structure of geological samples in recent decades.

5. Attenuated total reflectance - Wikipedia

   en.wikipedia.org/wiki/Attenuated_total_reflectance

   Most modern infrared spectrometers can be converted to characterise samples via ATR by mounting the ATR accessory in the spectrometer's sample compartment. The accessibility, rapid sample turnaround and ease of use of ATR with Fourier transform infrared spectroscopy (FTIR) has led to substantial use by the scientific community.

6. Nano-FTIR - Wikipedia

   en.wikipedia.org/wiki/Nano-FTIR

   The schematic representation of a nano-FTIR system with a broadband infrared source. Nano-FTIR (nanoscale Fourier transform infrared spectroscopy) is a scanning probe technique that utilizes as a combination of two techniques: Fourier transform infrared spectroscopy (FTIR) and scattering-type scanning near-field optical microscopy (s-SNOM).

7. Infrared spectroscopy correlation table - Wikipedia

   en.wikipedia.org/wiki/Infrared_spectroscopy...

   An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
