  2. 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.

  3. 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 ]

    The dispersive method is more common in UV-Vis spectroscopy, but is less practical in the infrared than the FTIR method. One reason that FTIR is favored is called "Fellgett's advantage" or the "multiplex advantage": The information at all frequencies is collected simultaneously, improving both speed and signal-to-noise ratio.

  5. OpenChrom - Wikipedia

    en.wikipedia.org/wiki/OpenChrom

    OpenChrom is an open source software for the analysis and visualization of mass spectrometric and chromatographic data. [4] Its focus is to handle native data files from several mass spectrometry systems (e.g. GC/MS, LC/MS, Py-GC/MS, HPLC-MS), vendors like Agilent Technologies, Varian, Shimadzu, Thermo Fisher, PerkinElmer and others.

  6. 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 ...

  7. Fityk - Wikipedia

    en.wikipedia.org/wiki/Fityk

    Fityk is curve fitting and data analysis application, predominantly used to fit analytical, bell-shaped functions to experimental data. 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.
