  2. Mass spectral interpretation - Wikipedia

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    [1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization mass spectrometry. [3] [4] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry ...

  3. Mass spectrum - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrum

    A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...

  4. Mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrometry

    Mass spectrometry can measure molar mass, molecular structure, and sample purity. Each of these questions requires a different experimental procedure; therefore, adequate definition of the experimental goal is a prerequisite for collecting the proper data and successfully interpreting it.

  5. Chlorine dioxide - Wikipedia

    en.wikipedia.org/wiki/Chlorine_dioxide

    Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C.

  6. Dichlorine monoxide - Wikipedia

    en.wikipedia.org/wiki/Dichlorine_monoxide

    Dichlorine monoxide is an inorganic compound with the molecular formula Cl 2 O. It was first synthesised in 1834 by Antoine Jérôme Balard, [2] who along with Gay-Lussac also determined its composition. In older literature it is often referred to as chlorine monoxide, [3] which can be a source of confusion as that name now refers to the ClO ...

  7. Disulfur dichloride - Wikipedia

    en.wikipedia.org/wiki/Disulfur_dichloride

    Sometimes, this compound is incorrectly named sulfur monochloride (or sulphur monochloride by the British English spelling), the name implied by its empirical formula SCl. S 2 Cl 2 has the structure implied by the formula Cl−S−S−Cl, wherein the dihedral angle between the Cl a −S−S and S−S−Cl b planes is 85.2°.

  8. Dichlorine hexoxide - Wikipedia

    en.wikipedia.org/wiki/Dichlorine_hexoxide

    Dichlorine hexoxide is the chemical compound with the molecular formula Cl 2 O 6, which is correct for its gaseous state. However, in liquid or solid form, this chlorine oxide ionizes into the dark red ionic compound chloryl perchlorate [ClO 2] + [ClO 4] −, which may be thought of as the mixed anhydride of chloric and perchloric acids. This ...

  9. Fragmentation (mass spectrometry) - Wikipedia

    en.wikipedia.org/wiki/Fragmentation_(mass...

    In mass spectrometry, fragmentation is the dissociation of energetically unstable molecular ions formed from passing the molecules mass spectrum. These reactions are well documented over the decades and fragmentation patterns are useful to determine the molar weight and structural information of unknown molecules.
