2. Fourier-transform infrared spectroscopy - Wikipedia

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

   The central peak is at the ZPD position ("zero path difference" or zero retardation), where the maximal amount of light passes through the interferometer to the detector. The goal of absorption spectroscopy techniques (FTIR, ultraviolet-visible ("UV-vis") spectroscopy , etc.) is to measure how much light a sample absorbs at each wavelength. [ 2 ]

3. PeakFit - Wikipedia

   en.wikipedia.org/wiki/PeakFit

   PeakFit is an automated nonlinear peak separation and analysis software package for scientists performing spectroscopy, chromatography and electrophoresis.. PeakFit automatically finds and fits up to 100 peaks to a data set, at a time, enabling users to characterize peaks and find the best equation that fits their data.

4. 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.

5. Geology applications of Fourier transform infrared spectroscopy

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

   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 ...

6. Fourier-transform spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Fourier-transform_spectroscopy

   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. The method of Fourier-transform spectroscopy can also be used for absorption spectroscopy. The primary example is "FTIR Spectroscopy", a common technique in chemistry.

7. Fityk - Wikipedia

   en.wikipedia.org/wiki/Fityk

   It is positioned to fill the gap between general plotting software and programs specific for one field, e.g. crystallography or XPS. [1] Originally, Fityk was developed to analyse powder diffraction data. It is also used in other fields that require peak analysis and peak-fitting, like chromatography or various kinds of spectroscopy. [2]

8. Two-dimensional infrared spectroscopy - Wikipedia

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

   The linear absorption (FTIR) spectrum is indicated above the 2D IR spectrum. The two peaks in the 1D spectrum reveal no information on coupling between the two states. After the waiting time in the experiment, it is possible to reach double excited states. This results in the appearance of an overtone peak.

9. List of free geology software - Wikipedia

   en.wikipedia.org/wiki/List_of_free_geology_software

   This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
