  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.

  4. Fourier-transform spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Fourier-transform_spectroscopy

    An "interferogram" from a Fourier-transform spectrometer. This is the "raw data" which can be Fourier-transformed into an actual spectrum. The peak at the center is the ZPD position ("zero path difference"): Here, all the light passes through the interferometer because its two arms have equal length.

    FTIR mode Sample preparation Schematic diagram Transmission FTIR: Transmission mode is the most widely used FTIR technique in geoscience due to its high analysis speed and cost-efficient characteristics. [4] The sample, either a rock or a mineral, is cut into a block and polished on both sides until a thin (typically 300 to 15 μm) wafer is ...

  7. 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).

  8. Two-dimensional infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_infrared...

    There are two main approaches to two-dimensional spectroscopy, the Fourier-transform method, in which the data is collected in the time-domain and then Fourier-transformed to obtain a frequency-frequency 2D correlation spectrum, and the frequency domain approach in which all the data is collected directly in the frequency domain.

  9. 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.
