  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, ...

  3. Infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Infrared_spectroscopy

    The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance ) on the vertical axis vs. frequency , wavenumber or wavelength on the horizontal ...

  4. Absorption band - Wikipedia

    en.wikipedia.org/wiki/Absorption_band

    Absorptions bands in the Earth's atmosphere created by greenhouse gases and the resulting effects on transmitted radiation.. In spectroscopy, an absorption band is a range of wavelengths, frequencies or energies in the electromagnetic spectrum that are characteristic of a particular transition from initial to final state in a substance.

  5. Why Do Dogs Stretch So Much When They See You? - AOL

    www.aol.com/lifestyle/why-dogs-stretch-much-see...

    Dog parents are perpetually curious about their dogs’ behaviors, whether they are amusing or slightly perplexing. For example, we often wonder, why do dogs stretch so much? In this guide, we ...

  6. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    Both symmetric stretching and bending vibrations have A 1 symmetry, but the frequency difference between them is so large that mixing is effectively zero. In the gas phase all three bands show extensive rotational fine structure. [14] In the near-infrared spectrum ν 3 has a series of overtones at wavenumbers somewhat less than n·ν 3, n=2,3,4,5

  7. 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.

  8. Vaska's complex - Wikipedia

    en.wikipedia.org/wiki/Vaska's_complex

    Infrared spectroscopy can be used to analyse the products of oxidative addition to Vaska's complex because the reactions induce characteristic shifts of the stretching frequency of the coordinated carbon monoxide. [4] These shifts are dependent on the amount of π-back bonding allowed by the newly associated ligands. The CO stretching ...

  9. Vibrational spectroscopy of linear molecules - Wikipedia

    en.wikipedia.org/wiki/Vibrational_spectroscopy...

    Example of a linear molecule. N atoms in a molecule have 3N degrees of freedom which constitute translations, rotations, and vibrations.For non-linear molecules, there are 3 degrees of freedom for translational (motion along the x, y, and z directions) and 3 degrees of freedom for rotational motion (rotations in R x, R y, and R z directions) for each atom.
